KM-2000M-KLS.1/N Low Speed dual port data module


KM-2000M-KLS.1/N is a low speed data module providing two RS-232/V.24 data channel interfaces for the Kilomux-2000/Kilomux-2100. The KM-2000M-KLS.1/N supports synchronous or asynchronous operation, selectable on each channel. 

The two channels can be set to one of three data rate groups:
Group 1: 300 bps to 38.4 kbps, sync and async;
Group 2: 7.2, 14.4, 28.8, 57.6 kbps, sync and async;
Group 3: 8, 16, 24, 32, 48, 56, 64 kbps, sync.

The data rate within each group is independently selected for each channel. Both channels must be set to the same group.
Channel interface is DCE, providing timing signals for direct connection to DTE. Connection of tail-end circuits is supported using buffering and retiming, to ensure data integrity at all times. The channel may also be configured to emulate DTE, with Transmit Clock and Receive Clock as inputs. Clock modes are soft-controlled in the KM-2000M-KLS.1/N. Two control signals per channel may be transmitted end-to-end for handshaking purposes, or alternatively, local support for the control signals may be provided. Typical end-to-end delay is 2.5 msec. KM-2000M-KLS.1/N comprehensive diagnostic capabilities reduce downtime to a minimum. Diagnostics include V.54 loopbacks (activated via connector pin or upon user command) and built in BERT test, initiated upon user command. Automatic self-test is performed during power-up and normal operation.

Three Modes of V.54 loopback are provided in the KM-2000M-KLS.1/N:
DCE-DCE: KLS.1 responds to LLB, RLB (Loop 2, Loop 3) by activating Local Loop or Remote Loop on each channel.
DCE-DTE: KLS.1 transfers LLB, RLB to the far end for activation of loopbacks in the remote modems.
DTE-DTE: KLS.1 activates LLB, RLD by soft command.

Each channel terminates on a 25-pin D-type, female connector. Pin-out assignment is in accordance with ISO-2110/RS-232 specifications.
