module for 2851 digital trunking

We are trying to integrate ShoreTel VoIP system with Cisco 2851 in India. Cisco 2851 will connect PSTN PRI E1 line in India, and will integrate with ShoreTel PRI switch. Can somebody please suggest the module that we can use for this purpose on 2851? Does NM-2CE1T1-PRI= can be used to connect both PSTN and ShoreTel T1/E1 switch? Do we need to use NM-HDV-2E1-60=? Any help is appreciated. Thanks in advance.

Hi hansraj,

The NM-HDV or NM-HDV2 cards would be most appropriate for your needs. These cards are recommended for digital voice connectivity requirements whereas the NM-2CE cards are suited to data needs. There are NM-HDV/HDV2 packages available with PVDMs or these can be tailored/added on specifically. If you have access I would recommend using the the Cisco Dynamic Configuration Tool to see the SKU options for these cards:

Hi

You don't need to use your NM slots on the 2851 - it can have VICs directly plugged in...

If you need a single E1 then just get a VWIC-1MFT-T1/E1, and a PVDM2-64 (assuming you want to run G729 on all 30 channels).

Also make sure you get an upgrade to an IOS with voice features.

Regards

Aaron
