Setting FDL Options (MCT1 Only)
Facility data link (FDL) options apply only when the MCT1 line type is
configured as ESF for testing. Select one of the following ESF line types using
Site Manager:
See the FDL Configuration parameter on page A-32 for information.
Setting the Signal Level (MCT1 Only)
By default, the T1 transmit power level is 0.0 dB. You specify a decibel level from
-15 dB to 1.5 dB, according to the length of the cable or as determined by the
carrier.
The carrier determines signal levels on a long-haul (0 to 6000 ft. of cable) T1
network interface. If 0.0 dB is not sufficient for long-haul, the carrier determines
values of -15 (ds1-minus15) and -7.5 dB (ds1-minus-7point5).
Signal power for DSX-1 short-haul (0 to 655 ft.) is based on cable length. For
DSX-1, decibel levels correspond to cable length, as follows:
