RTM and telephone damage
E1/T1 interfaces on face plate
On the face plate, RJ-45 connectors are used for different interfaces. Mismatching the
interfaces, i.e. connecting a telephone or an E1/T1 network to the serial interfaces
labeled as COM or connecting a serial device to a RJ-45 connector labeled as E1/T1
may damage the telephone or the RTM.
Therefore, only connect E1/T1 networks to RJ-45 connectors labeled as E1/T1 ports
and only connect serial devices to RJ-45 connectors labeled as COM.
