DUAL CHANNEL T1/E1/J1 LONG HAUL/SHORT HAUL LINE INTERFACE UNIT

templates and LBOs in detail for reference. For preset pulse templates and

LBOs, scaling up/down against the pulse amplitude is not supported.

Table-2 Transmit Waveform Value For E1 75 Ω

SCAL[5:0] = 100001 (default), One step change of this value of SCAL[5:0]

results in 3% scaling up/down against the pulse amplitude.

SCAL[5:0] = 100001 (default), One step change of this value of SCAL[5:0]

results in 3% scaling up/down against the pulse amplitude.

SCAL[5:0] = 110110

results in 2% scaling up/down against the pulse amplitude.

1. In T1 mode, when arbitrary pulse for short haul application is configured,

users should write ‘110110’ to SCAL[5:0] bits if no scaling is required.
