CAUTION:
CAUTION:
A detailed flowchart for isolating and resolving Packet Bus faults is included in 
 in Maintenance Procedures 
(03-300192). 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 se
repair procedures.
This section relates to the TN556 ISDN BRI, TN2198 ISDN BRIU, TN2208 Ethernet, 
(LGATE)-Ethernet Multifunction (MFB) circuit packs.
The TN2208 LGATE MFB provides the system with the interface to Adjunct-Switch Application 
Interface (ASAI) and Avaya adjuncts (for example, CONVERSANT
®
 Voice System).  This circuit 
pack contains 12 ports for line circuit interface (although only 8 are usable by the switch), each 
of which operates with two B channels and 1 D channel.  In this context, the term “ISDN-BRI 
port” is used to refer to ports on the TN2208 MFB circuit pack that are connected to ASAI or 
Avaya adjuncts.  The TN2208 LGATE MFB is handled by the switch software as if it is an 
ISDN-BRI compatible board, and every maintenance action referring to ASAI and Avaya adjunct 
links in this section applies.
The TN556, TN2198, and TN2208 ISDN-BRI Lines are packet port circuit packs that provides 
access to ISDN-BRI endpoints.  The ISDN-BRI Line circuit packs 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.
