8-port DS3 and E3 ATM UNI IOP Modules
The 8-port DS3 and E3 ATM UNI IOP modules provide trunk or user connections at
data rates of 44.738 Mbps (DS3) and 34.368 Mbps (E3) at each of the eight ports.
You can configure each port as one of the following:
• User-to-Network Interface (UNI)
• Interim Inter-Switch Signalling Protocol (IISP) connection
• Direct trunk
• OPTimum cell trunk
The 16-slot CBX 500 switch provides a maximum of 112 DS3 or E3 ports per switch.
The port buffers (8K each), combined with the 128K programmable cell buffers in the
switch processor (SP) quad-plane architecture, provide the flexibility, performance,
and data integrity required for high-speed networking.
