[c-nsp] Voice Configuration

[Paul Stewart]

Hi folks...

I'm working on a standard design for delivering voice services to clients.
In one of our POP's we have a Cisco 7513 and some other gear and would like
to look at servicing a number of clients over data T1 handing off FXO and
PRI services to them...

Here is one client setup we're looking at currently:

Cisco 7513 ---> (dual T1 data) --> Cisco 2821

Customer Prem: Cisco 2821 --> PRI
Customer Prem: Cisco 2821 --> 8 FXO lines (for fax primarily)

The Cisco 2821 will talk back to our softswitch at our main location.  We
would also like to deliver Internet services across these links (depending
on the customer) and I believe you can bond up to 4 T1's between a 7513 and
2821 or is it 6 now??  I'd like to know what our maximum bonding level is
(using CEF/OSPF).

The following configuration is what I"m looking at I believe (for voice
initially):

(1)CISCO2821 - 2821 w/ AC PWR,2GE,4HWICs,3PVDM,1NME-X,2AIM,IP BASE,64F/256D 
(1)MEM2821-256U1024D - 256 to 1024MB DDR DRAM 
(1)MEM2800-64U256CF - 64 to 256 MB CF 
(1)NM-HDV2-2T1/E1 - High-Density Digital Voice NM with 2 T1/E1
(1)EVM-HD-8FXS/DID- High density voice/fax extension module 8 FXS/DID 
(1)PVDM2-64 - 64-Channel Packet Voice/Fax DSP Module
(1)HWIC-D-9ESW - Nine port 10/100 Ethernet switch interface card 
(2)WIC-1DSU-T1-V2 - Updated 1-Port T1/Fractional T1 DSU/CSU WAN Interface
Card 

The idea would be 2821 with upgraded memory.  Then the NM-HDV2-2T1/E1 could
provide up to 2 PRI based T1 services to their PBX system (is this the
correct card for this job?).  The EVM-HD-8FXS/DID card would provide up to 8
analog telephone connections (each with their own phone number).  The
PVDM2-64 would provide the DSP functions neccessary for the voice to IP
conversion correct?  Then finally the pair of WIC-1DSU-T1-V2 cards would
provide T1 based connectivity back to the 7513 on our side.

Does this make sense or am I looking at the wrong hardware here?  I believe
the configuration won't be too much different than a AS5400XM is on the
software side but the hardware components are a little confusing on the
surface...;)

Appreciate it,

Paul
