Introduction
This chapter provides information regarding the configuration and troubleshooting for the
IMACS-200 High-Speed Data Ports. The IMACS-200 provides two High-Speed Data ports
which connect via an RS-530 interface DB-25 connector, and employ V.35 standard for
high-speed synchronous data exchange.
The HSU ports allow you to connect high-speed data terminal equipment (DTE) to WAN links
and/or other HSU ports.
9.2
HSU Ports
The IMACS-200 supports two V.35 CPE devices. Each port is configured to operate as a DCE,
with data speeds set at either 56 or 64 kbps.
CAUTION!
If used in a system using a T1 “Line Code” other than “B8ZS,” HSU card ports assigned to multirate
circuits greater than or equal to 4 or more consecutive time slots at 64kbps must have DTE
connected to the port prior to activation. Failure to attach DTE will cause a false carrier alarm.
The IMACS-200 can be used in data applications where the circuit has many timeslots (up to
24 for T1, and 32 for E1). The transmit and receive clock edges can be individually selected
(refer to Tx and Rx CLOCK PLRTY descriptions later in this chapter).
