DS3, E3, and STS-1e Interface Modules
1-Port Channelized DS3 Multiservice Module (23N60)
The 1-Port Channelized DS3 Multiservice and the 1-Port Channelized DS3
CES modules have a line rate of 44.736 Mbps. The physical port is divided
(channelized) into 28 virtual DS1 ports. Each virtual DS1 port can be chan-
nelized into 24 individual DS0s, providing a total of 672 channels. Each vir-
tual DS1 port can also be set up as a single, structured or unstructured chan-
nel. The 1-Port Channelized DS3 CES module provides circuit emulation
service only. The 1-Port Channelized DS3 Multiservice module provides the
following interfaces:
Because the 1-Port Channelized DS3 Multiservice module uses ATM Forum
specifications UNI 3.0, UNI 3.1, or 4.0, any DS1 port acts as a user network
interface (UNI), or an interim inter-switch protocol (IISP) user or IISP net-
