Interactions with Other MOs
The TN2242 MO directly interacts with these MOs:
■
■
■
Synchronization
The DS1 facility plays a vital role in the synchronization subsystem. The IPSI or
Tone-Clock circuit pack uses either the primary or secondary timing reference,
whether internal (local – IPSI or Tone-Clock circuit pack) or external. TN2242
circuit packs can be administered as “primary” or “secondary” synchronization
references.
The TN2242 circuit pack sends DS1 link status information to the synchronization
reference switching algorithm. This algorithm determines whether timing
references should be switched due to failure or restore conditions.
TN2242 Trunk Ports
The TN2242 circuit pack MO is responsible for monitoring the health of the DS1
facility. If a DS1 facility goes down, then that facility’s DS1 circuit pack instructs
every MO associated with the DS1facility to place its trunks (or ISDN-PRI
signaling link) in an out-of-service state.
Call Processing
The busyout board command tears down every call and signaling link associated
with a TN2242 circuit pack.
TN2242 Serviceability
Hardware Connections
This circuit pack can be:
■
Mated to another circuit pack of the same type when interconnecting two
S8700 Multi-Connect systems
■
Directly connected to the TDM network device
■
Directly connected to another vendor PBX using ISDN-PRI signaling
