XRT83L314
14-CHANNEL T1/E1/J1 LONG-HAUL/SHORT-HAUL LINE INTERFACE UNIT
REV. 1.0.0
For N+1 redundancy, the receivers on the primary cards should be programmed for internal impedance. The
receivers on the backup card should be programmed for "High" impedance mode. To swap the primary card,
set the backup card to internal impedance, then the primary card to "High" impedance. See Figure 39 for a
simplified block diagram of the receive section for a N+1 redundancy scheme.
