Module Installation and Operation
2-8 MP2100M-LS-2 Modules - Installation and Operation Manual
the first group of channels (1 through 5) of the local module, which uses
one time slot, loses synchronization to the corresponding group of the
remote module. The indicator designated SYNC LOSS TS-B has the same
function with respect to the second group of channels (6 through 10), which
uses the other time slot; the indicator is off when only the first group of
channels is in use.
The MTLS-2 and MTLS-2/2TS modules do not have channel connectors, as
these connectors are located on the interface module, IM-S68/2 or IMB-568/2,
described in Appendix A-1.
Modules LS-2,
LS-2A, LS-2A/2TS
Table 2-1 describes the functions of the LS-2, LS-2A and LS-2A/2TS panel
components.
