Configuring MCE1 and MCT1 Services

See the Line Coding parameter on page A-30 for information.
Setting the Signal Level
The Signal Level parameter specifies the T1 transmit power level in decibels (dB).
Line buildout conditions the signals to mitigate attenuation. Line buildout also
depends on the physical length of the T1 line.
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 and -7.5 dB.
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:
0.0 dB -- 0 to 133 ft.
0.5 dB -- 133 to 255 ft.
0.8 dB -- 255 to 399 ft.
1.1 dB -- 399 to 533 ft.
1.5 dB -- 533 to 655 ft.
By default, the signal level is set to 0.0 dB. Set the long-haul or short-haul signal
level for this MCT1 interface according to the length of the cable or as the carrier
specifies.
See the Signal Level (dB) parameter on page A-31
for information.
Setting the Alarm Threshold Time
By default, the MCT1 interface waits 2 seconds before logging a performance
defect or anomaly as an event message. Change the alarm threshold time to any
value from 2 to 10 seconds.
See the Setup Alarm Threshold (seconds) parameter on page A-31
for
information.
