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.
