Cisco Router Module Cards NIM-1CE1T1-PRI 1 port Multi-flex Trunk
Voice/Channelized Data T1/E1 Module
NIM-1CE1T1-PRI Overview
The Cisco® Fourth-Generation 1-, 2-, 4-, and 8-Port T1/E1 Multiflex Trunk
Voice and WAN Network Interface Modules (NIMs) support data and
voice applications on the Cisco 4000 Integrated Services Routers
(Figure 1). These cards combine WAN-interface-card (WIC),
voice-interface-card (VIC), ISDN Primary Rate Interface (PRI),
dial-access integration, and channelized-data (CE1T1) functions to
provide superior flexibility, versatility, and investment
protection through their many uses. Customers who choose to
integrate data and voice in multiple steps preserve their
investment in a T1/E1 WAN interface.
NIM-1CE1T1-PRI is a Cisco Multiflex Trunk Voice and WAN network
interface module for ISR 4000 series. Cisco® Fourth-Generation 1-,
2-, 4-, and 8-Port T1/E1 Multiflex Trunk Voice and WAN Network
Interface Modules (NIMs) support data and voice applications on the
Cisco 4000 Integrated Services Routers (Figure 1). These cards
combine WAN-interface-card (WIC), voice-interface-card (VIC), ISDN
Primary Rate Interface (PRI), dial-access integration, and
channelized-data (CE1T1) functions to provide superior flexibility,
versatility, and investment protection through their many uses.
Customers who choose to integrate data and voice in multiple steps
preserve their investment in a T1/E1 WAN interface. These NIMs are
not supported with Cisco 2900 and 3900 Integrated Services Routers.

* 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.
