When to use the TN2401 versus the TN2401/TN2400 sandwich pack

Field upgrades normally require the TN2401/TN2400 Network Control sandwich pack, Comcode 848486809, but there are exceptions to this rule!

IMPORTANT NOTE:

MCC1 SI Processor Carrier J58890AH-2 List 12 (which replaces List 5) does require the TN2401/TN2400 Network Control sandwich pack, Comcode 848486809. This carrier has been identified in older DEFINITY documentation as not requiring the sandwich pack!

Only the carriers and backplanes listed in this table use the TN2401 NetCon circuit pack, Comcode 108516675:
