Data Port
Data Rate
In a T1 multiplexer or variable rate multiplexer:
8 kbps to 1.536 Mbps in 8 kbps increments
In a 2 MB multiplexer:
8 kbps to 1.984 Mbps in 8 kbps increments
In a 2 MB variable rate multiplexer:
8 kbps to 2.040 Mbps in 8 kbps increments
Data Format
No restrictions on data content
Supports clear channel for AMI networks
Data Interface
Configurable for RS-449 or V.35, DCE or DTE, by selecting the
appropriate module adapter:
MA-412/MA-412A (RS-449, DCE)
MA-413/MA-413B (V.35, DCE)
MA-414 (RS-449, DTE)
MA-415 (V.35, DTE)
Signals Supported
RS-449: SD, TT, ST, RS, CS, RD, RT, RR, DM, TM, SG
V.35: SD, SCT, SCTE, RD, RTS, SCR, CTS, DSR, RLSD, LT, SG
Timing
DTE:
Synchronizes network to receive timing input. Provides terminal
timing output synchronized to network.
DCE:
Provides send and receive timing synchronized to the network. Can
synchronize network to terminal timing.
Transmit and Receive
Buffers
12 kb deep buffers, with user-selectable starting depth: either 256
bits for synchronous operation, or 6000 bits to support
plesiochronous operation
Network Interface
Time Slot Selection
Selectable use of adjacent or alternate time slots
Time slot 16 can be skipped for CAS usage in a 2 MB system
DS0 Usage
56 or 64 kbps per time slot, with unused bits set to logic “1”
Clear Channel
Capability
For AMI network: Alternate time slot usage per AT&T TR-54019, or
56 kpbs per time slot, with 8
th
bit set to logic “1”
