Serial High Speed WICs
8-Port RS-232 Asynchronous/Synchronous HWIC
The 8-port RS-232 asynchronous/synchronous HWIC (HWIC-8A-RS232), illustrated in
provides 8 asynchronous/synchronous RS-232 interfaces in both DCE and DTE formats. Data rates of
up to 230.4 kbps are supported in asynchronous mode, and up to 256 kbps in synchronous mode.

8-Port Asynchronous HWIC
The 8-port asynchronous HWIC (HWIC-8A), illustrated in
interfaces in DTE format, at data rates of up to 230.4 kbps.
Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the 8-port asynchronous HWIC (HWIC-8A) 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.

16-Port Asynchronous HWIC
The 16-port asynchronous HWIC (HWIC-16A), illustrated in
RS-232 interfaces in DTE format, at data rates of up to 230.4 kbps.
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
Caution
connect the 16-port asynchronous HWIC (HWIC-16A) 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.
