8-port T1 and E1 IOP Modules
In the CBX 500 switch, the 8-port T1 and E1 IOP modules provide user connections at
data rates of 1.544 Mbps (T1) or 2.048 Mbps (E1) on each of the eight ports. You can
configure each port individually as a User-to-Network Interface (UNI). With a 16-slot
modular architecture, the CBX 500 can support 112 T1/ E1 ports per switch.
Each module has 8K cell buffers per port. The port buffers, in addition to the 128K
cell buffers supported by the CBX 500’s quad-plane architecture, provide the T1 and
E1 modules with flexibility, performance, and data integrity.
