Procedure 11.42: CONVERT DATA-FANOUT WITH MULTIPLE PERIPHERAL INTERFACE
DATA BUS TO DATA-FANOUT
5E10(1) AND LATER SOFTWARE
OVERVIEW
The data fanout with multiple peripheral interface data bus (DF-MP) to data fanout (DF) conversion procedure
converts a packet switch unit (PSU) or PSU model 2 (PSU2) shelf containing DF-MP circuitry, capable of utilizing
multiple time slot interchange (TSI) peripheral interface data bus (PIDB), to a PSU/PSU2 shelf containing DF
circuitry, capable of utilizing a single TSI PIDB. Specifically, the new data fanout configuration (DF CON) will be able
to accommodate 4 active TSI PIDBs on each PSU/PSU2 shelf.
The DF/DF-MP circuitry provides duplex access to the simplex protocol handlers (PH). The DF and DF-MP circuitry
may not exist simultaneously on the same shelf. The DF supports 6 directly connected PIDBs (DPIDBs) from the
peripheral unit to the PSU and 1 module controller time slot interchange (MCTSI) to PSU connected TSI PIDB. The
DF-MP only supports 4 MCTSI to PSU connected TSI PIDBs.
All TSI PIDBs on a given PSU/PSU2 shelf with DF-MP circuitry must terminate on the same data expander (DX)
board.
Unless indication is necessary, this procedure refers to both packet switch unit types, PSU or PSU2, as PSU.
NOTE:
Should the PSU that is assigned to the data-fanout conversion have a
critical
designation, then it
is required that the PSU be temporarily re-designated for the conversion process. Once completed the
PSU is returned to its original state.
PROCEDURE
11.42.1 PREREQUISITE REQUIREMENTS
1.
This procedure should be executed during low periods of traffic, service interruption could be impacted.
2.
Electrostatic Discharge (ESD) protection requirements must be followed.
3.
Verify all required hardware listed in the PSU J-drawing J5D003BY-1 List 17 or PSU2 J-drawing J5D003BY-1
List 4 table is available. The DF-MP board must have a pack code of UN399 or greater.
4.
At the master control center (MCC), verify normal conditions in the switching module (SM) to determine if
system status is acceptable to start the association procedure.
If a NORMAL indication is not obtained, type and enter:
OP:SYSSTAT
Correct any deficiencies as required.
11.42.2 PRECONDITIONING
11.42.2.1 Back Up Office Dependent Data
