Superloops / Controllers

The image right is a NT8D01BC Controller-4 card.
It is installed in each IPE shelf between slots 7 and 8.

There are two Network shelf Cards:

The Superloop Network card combines four regular network loops to make 120 timeslots available to peripheral equipment (PE) cards housed in Intelligent Peripheral Equipment (IPE) Modules. Faceplate connector J2 is used for shelf 0.

An IPE Shelf has four card segments. A Superloop can be used for each segment (zero blocking), or shared bewteen 1 to 8 segments (two shelves). The back-plane wiring configuration (J1, J2 - SL0/SL1/SL2/SL3) must match the software configuration.

Superloop / Controller configurations are programmed and printed in LD 97.

Note: Do not enable the switch on NT8D04 or QPC414 Network cards until after the network loop cables are installed.

Warning Note: This page was written before the days of IP, but it's still applicable! With MGC or MGX cards, the SUPT (superloop type) is IPMG. You will need to know the Zone before hand. At IPR0, enter the Shelf 0 IP address. At IPMG_TYP0 (IPMG type) enter MGC (default), MGX, or MGS. Shelf 1 is IPR1, enter through if not present.

Diagnostic commands:

Occasionally, loops STAT as enabled/responding, but the IPE shelf is dead. Bouncing the controller in LD 32 should restore service (eg, DSXP x/ENXP x).

LD 30:

DISL loopDisable loop / superloop
ENLL loopEnable loop / superloop
LENLList enabled loops
LDISList dissabled loops
LOOP loop | ALLTest network memory on one or all loops, will also enable any dissabled digital sets
SHLF l sTest loop l, shelf s
ENDAbort current test
STATGet status of all network loops

LD 32:
