Serial Interface Cards
Serial High Speed WICs
7
OL-12843-01
Interfaces supported are as follows:
•
In both DTE and DCE formats: V35, X21, RS-232, and RS-449
•
In DTE format only: EIA-530 and EIA-530A
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.

4-Port Multiprotocol Low Speed Asynchronous/Synchronous HWIC
The 4-port multiprotocol low speed asynchronous/synchronous HWIC (HWIC-4A/S) is illustrated in
Figure 38
. Protocols supported are Async (SLIP), Async (PPP), HDLC, Bisync, and transparent.
Interfaces supported are as follows:
•
In both DTE and DCE formats: V35, X21, RS-232, and RS-449
•
In DTE format only: EIA-530 and EIA-530A
The maximum data rate supported is 256 kbps per port (synchronous).
Caution
