Main Link
Interface
Bit mapping
• 2 bits for 0.6, 1.2, 2.4, 4.8, 9.6 kbps
• 4 bits for 19.2 kbps
• 8 bits for 38.4, 48, 56, 64 kbps
Timeslots used
• 4 × 9.6 kbps in one timeslot
• 4 × 19.2 kbps in two timeslots
• 4 × 38.4/48/56/64 kbps in four timeslots
Indicators
LOS indicator (per
channel)
• Lights up when the corresponding channel loses
V.110 protocol synchronization to the remote end
• When operating at 64 kbps, the LOS indicator lights
when the main link loses synchronization
TEST indicator (per
channel)
Lights up when a loopback is activated on the
corresponding channel
Diagnostics
Loopbacks
• Local loopback
• Remote loopback
Timing
Timing source
RS-232 interface timing locked to nodal timing
Timing modes
DCE: Transmit and receive clocks to DTE
External DCE: Receive clock to DTE, transmit clock from
DTE
Configuration
Programmable by the Megaplex system management
