1.3 CONFIGURATION SETTINGS FROM CANOPY FACTORY
1.3.1 Bit Handling Capability
As shipped, Canopy T1/E1 Multiplexers transparently pass all T1 or E1 bits regardless of
◦
user framing as
−
D4
−
Extended Superframe (ESF)
◦
user encoding as
−
AMI
−
B8ZS
−
HDB3
However, user encoding is helpful for generating meaningful bipolar variation (BPV) data.
Canopy T1/E1 Multiplexers are factory preset to the B8ZS encoding for T1, though easily
changed to another encoding scheme, and are preset as master or slave for timing.
NOTE: To receive the highest level of performance from these units, the user should
understand
◦
clock recovery timing.
◦
packet/frame loss concepts.
◦
delay and latency.
◦
jitter.
