IMUX Features
This section provides information on the features of the IMUX.
Data Rates The Inverse Multiplexer has selectable data rates: n × 1.336 Mbit/s
(in 56K mode), n × 1.528 Mbit/s (in 64K T1 mode).
Performance
Monitoring
An overhead framing scheme provides critical error monitoring
capabilities.
NOTE: Although Verilink uses a proprietary format on the network
side, the data port functionality supports industry standards
for the physical interfaces.
Automatic Rate
Adaptation
For greater network protection, automatic rate adaptation is
included to adjust the data rate to lower speeds when the
performance of circuits degrades or fails. When the network
circuits return to acceptable performance, the IMUX automatically
restores the original data rate.
Front Panel LEDs The IMUX module provides tri-state (green, amber, and red) D ATA ,
S TAT , and N ET LEDs.
Specifications Table 1-1 and Table 1-2 list the specifications of the IMUX and DIM
rear connector module.
