MiTOP-E1/T1 Ver. 1.0 Configuring MiTOP-E1/T1 for Operation 4-9
LBT (T1 recovered Rx clock is used as the Tx clock)
Adaptive (Tx timing is provided by the adaptive timing recovery
mechanism. This locks the port Tx timing to the average rate of packets
received from the PSN through the bundle serving this T1 port.)
Line Code (Line code and zero suppression method used by the port):
B8ZS
AMI
Rx Sensitivity (Maximum attenuation of the receive signal that can be
compensated for by the interface receive path):
Short haul (-15 dB)
Long haul (-36 dB)
Line Type (T1 framing mode):
Unframed
ESF (24 frames per multiframe)
D4 (12 frames per multiframe)
Line Length (For DSU mode – Length of a cable in feet between the T1
port connector and the network access point; for CSU mode – Tx gain
level relative to T1 output transmit level):
DSU: 0–133 ft
DSU: 133–266 ft
DSU: 266–399 ft
DSU: 399–533 ft
DSU: 533–655 ft
CSU: -7.5 dB (Attenuation of 7.5 dB relative to the nominal transmit
level)
CSU: -15 dB (Attenuation of 15 dB relative to the nominal transmit
level)
CSU: -22 dB (Attenuation of 22 dB relative to the nominal transmit level)
