The 60-pin high-density connector provides five EIA-232 interfaces. (Connector pin locations are shown in
Figure C-3.)

EIA-232 refers to EIA-232-D without the loopbacks and ring indicator.

In TDM mode, if External Lead is configured for Rate (Ext Leads: Rate), then this lead is used for speed
selection on a port connecting to an analog private line (APL) extended circuit when the DDS backbone
goes into backup. This pin signals the APL modem to fall back to the predetermined backup speed if the
APL modem has fallback capability.
