2.2.2.4 UCM-MDTM2
The UCM-MDTM2 (Multifunction Digital Trunk Gateway Module) supports one digital trunk
It provides digital trunk (E1/T1, 2048K/1544K bps ISDN PRI, CCS No.7) and it is available selectively with
switch or Gateway Module initialization information.
For trunk line interface,
E1 Cable line impedance matching jumper should be set to 120Ω .
T1 Cable line impedance matching jumper should be set to 100Ω.
UCM-MDTM2 can match the frequency synchronization over the network system through LANU after
extracting the clock from a particular trunk.
