Verilink NCC 2020 User Manual 3-17
53 NCC 2020
TAC 2010
Selects DSX-1 Equipment cable length of 399-532 ft.
54 NCC 2020
TAC 2010
Selects DSX-1 Equipment cable length of 533-655 ft.
55 NCC 2020
TAC 2010
Sets data bus to NONE (CSU mode) [default].
56 NCC 2020
TAC 2010
DIU 2140
Sets data bus to A (Mux mode).
57 NCC 2020
TAC 2010
DIU 2140
Sets data bus to B (Mux mode).
58 NCC 2020
TAC 2010
DIU 2140
Sets data bus to C (Mux mode).
59 NCC 2020
TAC 2010
TAC 2130
Sends in-band CSU loop-up code to far-end CSU, this should cause the
far end CSU to enter a Line Loopback condition.
60 NCC 2020
TAC 2010
TAC 2130
Sends framed QRSS to far end.
61 NCC 2020
TAC 2010
TAC 2130
Stops QRSS pattern and send inband CSU loop-down code to far end.
62 DIU 2140 Uses timeslot 24 on the assigned CSU. Sets all 5 data ports to 9.6
kbit/s.
63 DIU 2140 Selects split timing (RX clock ~ TX clock); typical value.
64 DIU 2140 Selects single source timing (RX clock = TX clock).
65 DIU 2140 Sets DTE timing option for all synchronous data ports to ST.
66 DIU 2140 Sets DTE timing option for all synchronous data ports to ST.
67 DIU 2140 Sets DTE timing option for all synchronous data ports to TT.
68 DIU 2140 Sets RTS to normal operation. For synchronous data ports, data is
transmitted ONLY if the DTE asserts RTS (ignored in Async) [default].
69 DIU 2140 Sets RTS to forced on (requires version 1.1 DIU 2140 firmware), data is
sent regardless of actual state of RTS from DTE. This behavior always
applies to Async ports.
80 DIU 2130
TAC 2130
Sets Data Port 1 to tail-circuit timing. Note that TAC 2130-T and TAC
2130-S modules do not support tail circuit timing, external timing or
TIU 2850 timing.
