Data Port Strapping
Two data port connectors are located on both the T1 and the E1 access modules.
The ports can be strapped for RS-232/V.24, V.35 or X.21 physical interface. Each
connector is strapped by using two headers with jumpers located on the access
modules.
Note:
Data ports can provide clocks up to 512 Kb/s. However,
RS-232/V.24 strapped data ports are not recommended for
speeds over 64 Kb/s.

Make sure that power is disconnected from the unit that houses
the access module before attempting to change the data port
jumper headers.
