!
CAUTION:
A detailed flowchart for isolating and resolving Packet Bus faults is included
in Chapter 9, “Packet Bus Fault Isolation and Correction”. This flowchart,
along with the other information presented in the chapter, can help in
resolving problems that involve more than a single station or circuit pack.
Whenever the repair procedures for this Maintenance Object refer to Packet
Bus and/or Packet Control maintenance, be sure to reference Chapter 9,
“Packet Bus Fault Isolation and Correction”, in addition to the relevant MO
documentation.
ISDN-BRI Line is a packet port circuit pack that provides access to ISDN-BRI
endpoints. The ISDN-BRI Line circuit pack supports 12 ports, each of which
provides access to ISDN stations. Voice and circuit-switched data from the ISDN
stations are carried on the Time Division Multiplex (TDM) Bus. Signaling is carried
over the Packet Bus.
LEDS
The ISDN-BRI Line circuit pack performs extensive initialization tests and lights
both the red and green LEDS during the initialization testing. See Chapter 7, “LED
Interpretation”, for more details on circuit pack status LEDs.
