1-3. TECHNICAL SPECIFICATIONS
General
Function Three-channel adaptive multiplexer
Multiplexing Method Bit-interleaved Time Division Multiplexing (TDM)
Management and Supervision
Overhead – 0.8 kbps for main link data rates of 9.6 to 32 kbps
– 1.6 kbps for data rates of 48 to 128 kbps
– 3.2 kbps for data rates higher than 128 kbps
Main Link Characteristics
Data Rate 9.6 to 256 kbps, automatically recognized
Timing Externally clocked
Interface Synchronous V.24/RS-232, V.35, V.36/RS-449, RS-530, or
X.21 interface (strap selectable), configured as DTE
Connector 15-pin D-type female connector. Adapter cable for ordered
interface is supplied
Data Channel Characteristics
Data Rate 0.8 to 252.8 kbps, depending on mode and main link rate
ADAPTIVE mode Main Link Rate - Voice Channels Rate - Overhead
if at least one voice channel is active.
Main Link Rate - Overhead if both voice channels are idle.
See detailed list of values in Table 1-1
NON-ADAPTIVE 1 mode Main Link Rate - Voice Channel Rate - Overhead.
See detailed list of values in Table 1-1
NON-ADAPTIVE 2 mode See detailed list of values in Table 1-2
Clocking Receive and transmit clocks derived from the main link clock
