Serial Interface Cards Serial High Speed WICs 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.

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 To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the 4-port multiprotocol low speed asynchronous/synchronous HWIC (HWIC-4A/S) 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.
