2.5.1.5 E1/T1
The RTM face plate provides four E1/T1 interface connectors. The respective signals derive
from a PMC-8260/DS1 module installed on the front blade. The number of E1/T1 interfaces
actually available at the RTM depends on the particular PMC-8260/DS1 variant used. Refer to
the respective documentation.
The following connector pinout gives information on which signal is assigned to which pin. The
"x" stands for the number of the interface.
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.
