Programming the DSX1 Interface (C150 only)
Switch pack 3 is used to program the DSX1 Interface. The following is
a description of the DSX1 Interface settings:
Table 3-3 SWITCH Pack 3 - DSX1 interface (C150 only)
DSX1 in or out Switch 3 position 1 is used to enable or disable the DSX1 interface. In
the On position, the DSX1 interface is completely disabled and all
three LEDS (TX, RX and LOCK) associated with the DSX1 interface
will not light. When the DSX1 is not used, the DSX1 should be disabled
for proper operation of the unit. When a DSX1 input is used, position 1
must be Off.
DSX1 framing Switch 3 position 2 determines the type framing. With position 2 Off,
the unit will generate and expect ESF framing to and from the DSX1
interface. With position 2 On, the unit will generate and expect D4
framing. The framing selected on the DSX1 interface does not have to
match the framing on the Network Interface. The T-1 CSU/DSU can be
used to connect an ESF T-1 facility to a PBX which only supports D4.
