OCTAL T1/E1/J1 SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR
RECEIVE
For N+1 redundancy, the receivers on the primary cards should be programmed for internal impedance mode.
The receivers on the backup card should be programmed for external impedance mode. Since there is no
external resistor in the circuit, the receivers on the backup card will be high impedance. Select the impedance
for the desired mode of operation, T1/E1/J1. To swap the primary card, set the backup card to internal
impedance mode, then the primary card to external impedance mode. See Figure 16. for a simplified block
diagram of the receive section for a N+1 redundancy scheme.
NOTE: For simplification, the over voltage protection circuitry was omitted.
