NIM-1CE1T1-PRI

channel-group refers to bonding of one or more time slots into a single High-Level Data Link Control (HDLC)-framed serial connection for IP data traffic connectivity. This connection is used for HDLC, Frame Relay, and Multilink PPP (MLPPP) serial WAN connections.

** ds0-group refers to bonding of one or more time slots into a single TDM voice connection using CAS such as ear and mouth (E&M), foreign exchange station (FXS), or foreign exchange office (FXO). This connection is used for TDM PBX or PSTN connections and typically is deployed only on T1.

*** pri-group refers to bonding of two or more time slots into a single TDM connection using ISDN signaling. This connection is typically used for TDM PBX or PSTN voice connections on T1 and E1, and also for data WAN connections on E1. Each call on the PRI is individually indicated as being a voice or data call with the ISDN bearer capability delivered with the call. Signaling is done on the D-channel, which is always channel 24 on a T1 and channel 31 on an E1.

**** tdm-group refers to cross-connecting one or more time slots from one TDM interface to another. This connection is used to groom channels from different access points onto a combined T1 or E1 uplink. Because the router merely cross-connects and does not interpret or route the traffic from the ingress interface to the egress interface, the traffic type (voice and data) is transparent to the router.

Cisco IOS XE Software Release Requirements

 

The modules are supported on the Cisco 4000 and require Cisco IOS XE Software Release 3.9.

 

The DSP farm services (conferencing & transcoding) on the modules are supported only on Release 3.11 and above.

 

Data applications require the IP Base technology package, which is included by default. Voice applications require a minimum of the UC technology package, which is optional.

 

Data Features

 

NIM data features follow:

 

●   T1/E1 or fractional T1/E1 network interface

 

●   n x 64 kbps or n x 56 kbps, nonchannelized data rates (T1: n = 1 to 24, E1: n = 1 to 31)

 

●   Standards-based, including ANSI T1.403 and AT&T Publication 62411

 

●   Non-Facility Associated Signaling (NFAS) on one single module is supported. NFAS across multiple NIM modules is not supported.

 

NIM data features do not include Dial on Demand Routing (DDR).
