1.1.5 Z22 External Timing
The Z22 system supports the following timing inputs/outputs used for network synchronization:
• 2 T1/E1 outputs
• 2 T1/E1 inputs
The timing inputs and outputs are accessed through an 8-position pluggable terminal block on the rear side
of the Z22 chassis.
The following table shows the external timing connector pinouts:
Pin Description
1 T1/E1 TX1_+ (Output)
2 T1/E1 TX1_- (Output)
3 T1/E1 RX1_+ (Input)
4 T1/E1 RX1_- (Input)
1 T1/E1 TX2_+ (Output)
2 T1/E1 TX2_- (Output)
3 T1/E1 RX2_+ (Input)
4 T1/E1 RX2_- (Input)
1.1.6 Z22 Alarms
The Z22 platform supports system and environmental alarms. System alarms include Critical, Major,
Minor, and Failsafe. The environmental alarms include 4 inputs and 2 outputs. Alarms are accessed through
a combination 20-position pluggable terminal block on the rear side of the Z22 chassis.
