MTS
Clause
14.11
Announcement in Class 4 application are
limited and can be offered as in-built
announcement server in the MGW.
By having a central announcement server,
BSNL is extending the calls right upto the
central Announcement server and hence
consuming precious bandwidth. We recommend
a distributed built in announcement server with
the MGW may be considered wherein the
announcements can be delivered at the point of
interconnection of trunks. The announcement in
these can be managed from centralized EMS
locations and the changes/feeding of
announcements can be carried out from the
centralized locations. This will have
considerable advantages for BSNL as compared
to the centralised location. This will have
considerable advantages for BSNL as compared
to the centralized server where the bearer traffic
has to flow to a central location consuming
precious bandwidth. Request BSNL to allow
both integrated announcement servers with the
MGW and standalone Announcement servers.
No change in Tender
requirement.
26.
MTS
Clause
14.11 (vi)
As per BSNL. Announcement server should
support H.248v1 upgradable to H.248v2.
However the current technology trends show
that in future SIP will be most popular and
widely deployed protocol between the
Softswitch and announcement server or for that
matter any external resource. We hence suggest
that protocol between the switch and
Protocol between
Softswitch and
Announcement Server
can be H.248 ver 2 or
SIP.
announcement server should be either H.248v2
or SIP.
27.
MTS
Clause
14.11
As per BSNL Announcement Server should
support IVRS functionality. However the
requirement as per this tender is for Toll
switches and subscribers are not directly
connected to this network. IVR primarily being
needed in a class 5 scenario, we suggest that
BSNL should relax the requirement of IVRS on
the announcement servers or ask for it as an
optional item.
IVRS functionality in
Announcement server is
not required.
28.
SGW GR
Clause
2.3.1(v)
As per GR, the signaling gateway needs to
support M2PA. M2PA is required to be
supported only by STPs. However BSNL has
already deployed STPs and M2PA functionality
would not be required to be supported by the
signaling gateways. We would hence request
BSNL to relax the requirement of M2PA.
No change in
requirement.
29.
SGW GR
Clause 2.0
As per the GR, the signalling GW needs to
support STP functionality. Please clarify as to
why would need to support STP functionality
when BSNL has standalone STPs deployed in
the network. This would lead to duplication of
STP functionality in the signaling gateway
which is not likely to be used. We therefore
recommend that the STP functionality
requirement from the signaling gateway may be
relaxed.
No change in
requirement.
30.
SGW GR
Clause
2.10.3
As per the GR, signaling gateway needs to
support 500 signalling links. BSNL is requested
to define the actual number of signaling links
which are required to be engineering on the
signaling gateways. 500 signalling links in a
signaling gateway in the STP architecture
followed by BSNL is very high. We therefore
recommend it may be reduced.
The initial capacity of
SS7 links in the
Signaling Gateway
would be 100. The
capacity would be
expandable to support the
maximum capacity as
indicated in the TEC GR.
31.
SGW GR
Clause 2.6
On line transfer of billing information is
required from Signalling Gateway. However
since signaling gateway does not process calls
but only carries signaling information.

MTS
Clause
14.2
IP Centrex is a class 5 service which will enable
to provide specialized services within group. IP
Centrex services as per the open standards
architecture specified by 3GPP should be
provided through an Application server. Apart
from the basic application server to provider the
features there could be requirement of web
portal servers for the efficient management of
the features and service by the user himself.
Since all these are related to pure class 5
environment, we suggest this may be kept out
of the scope of this tender. However,
compliance to support external feature servers
(applications servers) on SIP interface as per the
standards may be asked to ensure that at a later
date BSNL is at liberty to procures the class 5

Clause
14.7(viii),
14.8(ix)
In an actual network, SGW and MGW can be
synchronized with using timing signal from TD
interfaces (E1/STM-1), As there is necessity to
have a common clock across the network and
even today the clock for complete SDH and
TDM infrastructure of BSNL is common. It is
imperative that the same clock should
mandatorily be used. In case of failure of this
clock, internal holdover clock, even though it
may be of lower stratum, will be able to hold
for a reasonable time. The above condition of

49.
MTS
Clause
14.9(i)
The tender requirements for the Softswitches,
Trunk Media Gateways etc… are far below than
what is mentioned. BSNL should ascertain the
scalability of the NMS / EMS rather than
seeking the equipment dimensioned for such
high requirements. BSNL may ensure standard
north bound interfaces from EMS / NMS to
protect the investment made in this procurement
presuming multiple vendors would be there in
future. We recommend the EMS/NMS
hardware be dimensioned as per the tender

Please clarify the % mix of G711 and G729
vocoders. Since the network is going to evolve
as the core network for carrying various types
of traffic (wire line/ wireless), best voice quality
needs to be ensured at the core of the network
and therefore it may be advisable to have all the
codec’s configured as G711 for best voice
quality. Alternatively, to provide flexibility to
BSNL, the requirement may be restated as the
vocoder pools should provide at least 50%
G711 (or G729) capacity.
All the ports shall be
configurable for any
combination of G.711
and G.729. Refer
clarification above also.
60.
As per TEC GR, the TMG has been asked for
providing 5% extra DSP resources and N+1
redundancy of the vocoders. Generally the
vocoders are pooled resources and hence 5%
extra DSP requirement is more than sufficient
for meeting redundancy requirements. Hence
we request BSNL to ask for either N+1
configuration or 5% extra DSPs, not both.
No change in Tender
requirement.
61.
Signaling
Gateway
As we understand, BSNL is already in the
process of deploying a standalone signaling
network based on SSTPs, that are also working
as signaling gateways. To avoid duplication of
resources, we request BSNL to make the
Signaling Gateway functionality as optional.

Softswitches, 6000 TMG, 60 announcement
servers and 60 signaling gateways, or just the
software licenses need to be provided for this
quantity. We request BSNL to ask for the
expansion prices for the hardware while the
software may be procured for the full quantities.
63.
DMTS
clause 14.9
(xvi)
For the NMS, database server is supposed to be
separated from Application server. We request
BSNL to allow the flexibility for database
server to be integrated with the application
server. This will result in performance
improvement and less chances of failure
because of network outages. Secondly, the
requirement for providing 4 processors should
be considered in reference to the latest
generation of dual core servers. In case of dual
core processors, each processors provides the
performance worth two processors and even
there are two oracle licenses that are needed for
each such dual core processor. Hence in case of
such offering, minimum requirement should be
to provide two dual core processors, expandable
to 4.
No change in
requirement.
64.
DMTS:
clause
14.11
Announcement servers: We request BSNL to
consider announcement servers integrated with
the Trunk Media Gateways, as per the TMG
GR. This will result in efficient utilization of
network resources as the calls do not need to
traverse through the whole network for the
announcements. Also there will be many
languages that would have to be supported and
each TMG location might need a different
language for announcement. In case of
announcement server, integrated with TMG, the
whole architecture becomes very simple and
there is also substantial bandwidth saving.
No change in
requirement.
65.
Section IV,
Part II,
Clause 2.6.2 describes that Batteries are to be
supplied along with the power plant. However,
the duration of Battery backup is not provided.
Please provide the battery backup time.
Refer MTS.
66.
As BSNL is planning two large softswitch
domains each supporting a large number of
Trunk Media Gateways, it is unacceptable to
loose service due to a softswitch site failure e.g.
failure of softswitch nodes, applications, links
to connecting equipment or IP network links
etc. Hence the Softswitch in a single IP domain
shall support a fully distributed configuration
where the softswitch nodes are distributed over
two physical sites, providing geographical

redundancy such that either one of which can
control the entire switch if the other site is lost.
In a multi-site configuration, the switch shall
continue to operate upon a single failure of any
component that is available in a redundant pair.
When a switchover occurs on a redundant
component, the switch shall preserve stable
calls. Hence, it may be worthwhile to consider
the two controllers to be geographically
redundant.
67.
NMS GR
As per NMS GR, GR/NMS-01/01.JUL.2005 the
NMS for IP TAX needs to manage the transport
network (IP/MPLS) also. This means that the
NMS for IP TAX will have to manage the
routers, LAN switches, Firewall etc. that
constitute BSNL’s IP/MPLS network. All these
requirements are outside the scope of supply as
per the tender document. Also as we understand
all these equipment are already installed and
integrated to constitute BSNL’s IP/MPLS
network. We also understand that BSNL has
already installed a NMS for the management of
these network elements, and conforming to the
NMS GR. As it is suggested by the TMN
architecture, the EMS layer should talk to the
NMS layer, we request BSNL to ask the bidder
to only supply the Element Management
System (EMS) with appropriate North bound
interfaces and APIs so that this EMS can be
interfaced with already deployed NMS under
MPLS/NIB project.
NMC will control the
NEs supplied in this

control protocol it is not permitted to register
the gateway simultaneously to the multiple

gateway (announcement server) needs to be
partitioned/decomposed into multiple gateways
and then the same can be parented to multiple
soft switch nodes. So instead of doing the

160. Bid
Clause
2.15.2
As per MTS clause 2.15.2, the Softswitch
should comply to SIP_T initially and SIP_I
within one year of the PO. Since both the
Softswitches would be from the same

As per the clause the call and message handling
resources in the Softswitch will act in load
sharing mode ......... in the solution
We request BSNL to provide option in form of
Load sharing or Active/Standby provided call
state model is maintained.
The resources referred to
in this clause and 14.7

available in pool and act
in load sharing mode. In
case of failure of one of
the entities in the pool /
overload condition, the
load will be distributed to
the remaining entities.

It is suggested that BSNL uses the existing
NMS system deployed in MPLS and NI
network for managing the EMSs supplied in
this network
Refer clarification above
please.
168. MTS
Clause
14.9(i)
The tender requirements for the
Softswitches(30), Trunk Media Gateways
(6000), AS (60), Signalling GW (60) etc…(are
far below than what is mentioned. BSNL should
ascertain the scalability of the NMS / EMS
rather than seeking the equipment dimensioned
for such high requirements. BSNL may ensure
standard north bound interfaces from EMS /
NMS to protect the investment made in this
procurement presuming multiple vendors would
be there in future. We recommend the
EMS/NMS hardware be dimensioned as per the
tender requirements and should have the
scalability to the requirements mentioned.
Refer clarification above.
169. MTS
clause
18.0
BSNL is requested to clearly specify what is
expected for LI requirements. Is it providing 8
fanned out calls for the 240 simultaneous
monitored calls ?
Also please clarify if the 240 calls are to be
monitored per M. Gateway or per domain?
Refer clarification above.
Maximum 240 calls per
domain will be there
which will be sent to 8
LEAs. However, all these
240 calls may be
intercepted from one
Media Gateway also.
170. SGW GR As per the clause, it shall be possible to extract
No change in
Clause
2.2.2
and process the signalling information from
64kbit/s signalling links multiplexed on a 2048
kbit (ITU-T G.703) links. The SG shall be able
to extract signalling information which can be
on at least 16 time slots (except time slot 0).
For redundancy and failover, each SG is
connected to at least 2 standalone STPs (SSTP).
It is recommended that there should be a
diversity of E1s carrying the signaling links and
hence set a limit of 8 signalling links per E1.
Max 8 SLs per E1
requirement.
171. SGW GR
Clause
2.1.6
Please define how many signalling links are
required per E1 for High Speed Signalling links
It will be 2 Mbps as per
Q.703.
172. SST GR
clause
2.3.5
As per the clause, it shall be possible for a
Softswitch to act as primary Softswitch and
secondary Softswitch. Secondary Softswitch
shall be re-configurable to control the media
gateways originally controlled by a primary
Softswitch by loading office data from a remote
NMS, in case of failure of primary Softswitch.
Please clarify as same SS is supposed to act as
primary & secondary for other domain. In such
case it will require extra hardware to support
primary SS MGWs.
Yes. However, each
Softswitches is to be
dimensioned for full 4
MBHCA and 6 MBHCA
in overload condition.
173. SST GR
Clause
2.3.6
As per clause 2.3.6 of Softswitch GR, the
Softswitch is required to support 6M BHCA. As
per the network requirement of BSNL for the
200KC tender, the requirement of 6Million is
too high. The BHCA required per Softswitch
required in the network will not exceed 4
Million even after taking into consideration full
expandability of the network. Hence BSNL
should not ask for a BHCA of more than 4
Million which would be more in line with the
network architecture and the call load in the
network.
No change in
requirement.
174 SST
GR
Clause
2.8.3
As per the clause the Softswitch should support
CS1 with CS2 functionality in the future.
However as per the NGN architecture, the
protocol defined between the Softswitch and IN
is SIP. SIP is the technology that would be used
in the future for all interactions between
Softswitch and SCP. We hence recommend that
BSNL agrees for SIP as an alternate to CS1 for
IN-Softswitch interface
No change in
requirement. Refer
clarification above also.
175. SST GR
Clause2.1.
Transport over TCP and UDP shall be provided
for H.248/Megaco & SIP- T protocols.
No change in
requirement.
7
TCP is a Connection Oriented protocol.
Using them in network will result in clogging
of the network due to window sizing and
acknowledge messages. In our solution H.248
and SIP-T both use UDP currently.
176. SST GR
Clause 2.5
As per the clause, the Softswitch shall be able
to control 200 MGs. However as per the traffic
statistics and given the BHCA capacities of the
softswitch, the SSW cannot control more than
35 Media Gateways.
Assuming 4K as the capacity of the Media
gateway (which is the smallest MG as per the
MGW GR clause 3.3), 60sec as CHT and 0.7erl
traffic per trunk, a Softswitch of 6Million
BHCA can control only 35 Media gateways.
hence we strongly recommend that this
requirement of controlling 200 MGs per MGC
is illogical and hence may be relaxed for this
tender.
Softswitch should be
capable of controlling
200 TMGs.
177. SST GR
Clause
3.2.1.7
Please note that LCR functionality is not
required for NLD operations specially since
BSNL has their own backbone. Since LCR is
more applicable to ILD operations, it is
suggested that LCR requirement may be made
optional.
Quotes for LCR is
optional.
178. TMG GR
Clause
3.7.3
………...The MGW shall also monitor traffic
given over the voice paths over LSPs to initiate
the process of bandwidth increase/decrease of
an LSP.
MGW doesn't control LSPs, it will only mark
the packets.
The MGW shall also
monitor traffic given
over the voice paths and
generate required quality
deterioration alarms.
179. TMG GR
Clause
3.10
NTP: It shall synchronize to the NTP (Network
Time Protocol) server available in the network
and use this timing information for time
stamping of all protocol messages including
NTP.
If MGW is to be synchronized with NTP then
there shall be no need of L2 Clock.

the IP TAX tender. We request BSNL to relax
this requirement as it was also relaxed in earlier
tender vide clarification no 55 page 12 issued
last time for the IP TAX tender. BSNL has
replied that “Lead Bidder should have a
turnover of INR 1000 million including
principal of Soft switch manufacture.”
We request BSNL to confirm that the above
clarification holds good for this time as well.

There are 20 TEC GRs which are required to be
complied in the Tender. As you are aware that
making the soft copies and submit the
compliance of each and every clause of these
GRs makes the entire process lengthy and also
increase the size of the bid. Instead, bidder
should be allowed to submit one undertaking /
compliance statement for each and every GR
mentioning that “We comply each and every
clause of TEC GR No. xyz”. You are requested
to please allow that same. Over and above
Statement of Deviation, if any, shall be required

TAC / TSEC
As we all are aware that this is a new and latest
technology for which no Purchase Order is yet
placed by BSNL in past and being a new
technology there is no vendor who has the TAC
or TSEC for the product as of now. This tender
is not only for one item but the successful
vendor is required to supply multi products.
Keeping in view the above facts you are
requested to please waive the condition of TAC
/ TSEC and also Form B. However, after
opening of bids the successful bidders should
go for the validation instead of TEC/TSEC.
This will make the tender process bit easy and
will allow a healthy competition.
