Over voltage protection
Line cards NTEX17AA, NT6X17BA, NT6X18BA, NT6X19AA and
NT6X21AD are used only with telephone wiring protected by a Nortel
Protector Cat. No. 303M-12AIKE in combination with a 26 AWG copper wire

Intelligent Peripheral Equipment Column

The IPEC contains up to four Universal Equipment Modules (UEMs) to
house the Intelligent Peripheral Equipment (IPE) modules. One UEM
provides the framework for housing one IPE module.
Each IPEC requires one Extended System Monitor (XSM) card that can be
configured either as a master or a slave. One master XSM is capable of
supporting up to 64 columns (IPEC) and up to 63 slave XSMs located in
other columns, using a daisy chain of serial communication links. Only the
master XSM reports status (of the master XSM and the slaves connected to
it) to the system CPU or responds to system status inquiry messages.
