Serial Interface Cards
Interfaces supported are as follows:
•
•
The maximum data rate supported is 8 Mbps per port.
Caution
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the 4-port multiprotocol high speed HWIC (HWIC-4T) only to intra-building or non-exposed
wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.

Interfaces supported are as follows:
•
•
The maximum data rate supported is 256 kbps per port (synchronous).
