What is the feature differences between the following 2 parts?:

NM-1CE1T1-PRI

VWIC2-1MFT-T1/E1

I have this problem too.

Hi Chris,

The primary difference here is that the NM-1CE1T1-PRI is not used for Voice and the

VWIC2-1MFT-T1/E1 is used for Voice. Have a look at the description for the NM-1CE1T1-PRI;

Module as "Data Only",

The versatility of Cisco 2610-51XM, 2800, 2691, 3660, 3700 and 3800 series routers is demonstrated by their broad support of E1/T1 connectivity and Integrated Services Digital Network Primary Rate Interfaces (ISDN PRI). Customers continue to deploy E1 and T1 circuits for Wide Area Network (WAN) connectivity, ISDN dial-backup, and digital modem termination in the Power Branch Office Environment. Cisco now makes it possible to terminate T1 and E1 PRI connections in a single network module. Available in single and dual port models, the NM-1CE1T1-PRI and NM-2CE1T1-PRI cards coupled with Cisco 2610-51XM, 2800, 2691, 3660, 3700 and 3800 Series routers, enhance and simplify customers' WAN connectivity options

The Cisco E1/T1 ISDN PRI Network Module's integrated channel service unit (CSU) provides direct connection to the Telecommunications network, thus allowing customers to consolidate customer premises equipment (CPE). This provides multifunction dial access aggregation, routing functionality, VPN and firewall security, and other capabilities right inside the Cisco router in power branch office environments. Both the 1-port and 2-port versions offer support for balanced and unbalanced E1 connectivity and conform easily to customers' specific applications.

The Cisco E1/T1 ISDN PRI network modules also supply connectivity for internal digital modems in the Cisco 3660, 3700 and 3800 series routers, with connectivity options for PRI, T1 channel associated signaling (T1-CAS), and E1-CAS R2 signaling. This provides for a high concentration of V.92-compatible modems, while still allowing expandability for other critical services.

FEATURES AT-A-GLANCE

Cisco IOS Software configurable for T1 or E1 operation

Balanced or unbalanced E1 termination in the same module

Integrated CSU/DSU (channel service unit/data service unit) per port

Full or fractional E1/T1-can be fully channelized

***Supports PRI for data, T1-CAS, and E1-CAS R2 signaling

E1 unframed and framed modes (G.703/G.704) available

Interoperates with NM-xDM digital modem network modules

Bantam (tty) jacks for easy network monitoring

V.54 loopback compatible

Supported on Cisco 2610-51XM, 2800, 2691, 3660, 3700 and 3800 Series routers

Rob,

Clicked on post and thought I was seeing double vision.

Sorry man. You know the saying 'Two great minds think alike'.

Anyway - 5for you.
