14-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT
REV. 1.0.1
Select the impedance for the desired mode of operation, T1/E1/J1. To swap the primary card, set the backup
card to internal impedance, then the primary card to "High" impedance. See Figure 26. for a simplified block
diagram of the receive section for a 1:1 redundancy scheme.

N+1 Redundancy Using External Relays
N+1 redundancy has one backup card for N primary cards.
Due to impedance mismatch and signal
contention, external relays are necessary when using this redundancy scheme. The relays create complete
isolation between the primary cards and the backup card. This allows all transmitters and receivers on the
primary cards to be configured in internal impedance, providing one bill of materials for all interface modes of
operation. The transmit and receive sections of the LIU device are described separately.
