Table 5-1. Normal Mode of Operation
INBAND MODE The Nx56/64 port is capable of providing an
inband communications channel (for T-
Watch and SNMP) between units. This is
accomplished by using 8 kbps of the first DS0
assigned to that particular Nx56/64 port. If
in 56 K mode, no data bandwidth will be
used. Inband must also be enabled at the
destination port.
Choices: On, Off, On Demand
TX CLK SOURCE This controls the source of the clock used by
the TSU 120 to accept transmit data from the
DTE. The default is
INTERNAL . If the
application requires that the DTE device
provides the clock with the transmit data, the
EXTERNAL setting is used.
