attaches to the HSC board. The other end splits into four connectors. Each connector is capable
of operating at full-duplex speeds of up to 8 Mbps. Each connector supports any of the following
four physical layer interfaces:
• RS232
• V.35
• X.21
The physical layer interface type is selected via a combination of one of two available PLIMs
(physical layer interface modules) and one of eight available HSC communication cables.
The PLIM choices are:
• PLIM1 - Supports either RS232 or V.35 physical layers.
• PLIM2 - Supports X.21 physical layers.
The HSC comm cable choices are:
• RS232 DTE
• RS232 DCE
• V.35 DTE
• V.35 DCE
• X.21 DTE
• X.21 DCE
The DCE cables allow the HSC to be connected directly to DTE devices. No modem or
modem eliminator is required. When a DCE interface is selected, the HSC board should be
configured to generate the transmit clock. Baud rates up to 1 Mbps are supported and are
configured on the HSC line panels. All four connectors on the board may be connected using
the same type of PLIM and comm cable or any combination.
