The NIM-1CE1T1-PRI is a Cisco 1-port multiflex trunk voice and channelized data T1/E1 network interface module for the NIM slots of Cisco 4000 Series Integrated Services Routers. These modules are not supported on the 2900 and 3900 Series routers, and they need Cisco IOS XE Release 3.9.
As a channelized (CE1T1) module it handles T1, fractional T1, E1 and fractional E1, plus structured G.703 with G.704 framing and unstructured E1 (G.703). Per port it supports 24 voice channels on T1 or 31 on E1, one PRI group, and drop-and-insert cross-connects of 24 or 31 time slots. Non-Facility Associated Signaling works on a single module and not across several NIMs.
An onboard PVDM4 slot takes the fourth-generation DSP module that the voice features need, giving echo cancellation up to a 128-ms tail. DSP farm conferencing and transcoding need IOS XE 3.11 or above, and voice needs at least the UC technology package. The DSU/CSU is managed, with DSX-1 cable length selectable from 0 to 655 feet in DSU mode and CSU line build-out of 0, -7.5 or -15 dB. The module weighs 0.40 lb (181 g) and measures 1.25 x 3.50 x 7.24 in. (3.18 x 8.89 x 18.39 cm). For other NIM and router interface options, see Cisco interface cards.
