1.3CONFIGURATION SETTINGS FROM CANOPY FACTORY
1.3.1Bit 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.
