Since the packet bus is required with PRI Over PACCON, the TN778
Packet Control circuit pack should be added first. If the system is not
equipped with a packet bus see ‘‘
Add Packet Bus to R6si’’ on page 5-113.
If EPNs reside in the system, replace every TN776 EI circuit pack with a
TN570 EI to provide packet-based communication between the PPN and
each EPN.
2. Remove an existing TN756 Tone Detector/Generator circuit pack and
install the TN768, TN780, or TN419B Tone-Clock circuit pack in assigned
carrier slot, if required.
3. Determine port assignment of port circuit packs to be added.
4. Install the TN464 circuit pack in assigned carrier slot (as required). For
example:
5. Install the TN748B (or the non-United States TN420B) Tone Detector
circuit packs, as required.
Install Cables
1. Install cables from the cabinet to the MDF as required.
Power Up System
1. At each EPN, set the main circuit breaker to ON.
2. At the PPN, set the main circuit breaker to ON.
3. The system performs a level 4 reboot, loading the system translations from
the translation card or tape. Rebooting takes several minutes.
4. After the system reboot is finished and all trouble is cleared, verify the
EMERGENCY TRANSFER CONTROL switch is set to AUTO. This restores
the system to the normal mode.
