17 — DNIC and 2B1Q modules
Procedure 17-5 To set the RTS/CTS delay
The RTS/CTS delay can be set for two-port DTUs. RTS/CTS delay cannot be set for the
2606 MainStreet DTU.
The RTS/CTS delay can only be set when a circuit is configured for half-duplex mode
(see section 17.5) or as a multidrop slave (see section 17.10).
CONFIG — CIRCUIT — <pp-c> ↵ — FUNCTION — I/F_MODE — RTS/CTS — <delay time> ↵
where
pp is 1 or 9, and c is A or B
delay time is from 0 to 1250 ms in 10-ms increments (10 ms*)

Control signals

Control signals provide the handshaking required for call setup, call tear-down and
synchronization. Control signals can be configured as:
•
high (ON)
•
low (OFF)
•
end-to-end (END_TO_END)
End-to-end means the state of the local signal follows that of the signal source at the
remote end of the network. This option is only available when using HCM rate
adaption.
Table 17-1 shows default control signal settings. If the device is configured as
synchronous, DTR and DSR are not functional.
17-6
Control signals are the only interface parameter that can be
Note —
set for a circuit that is configured as a timing source. It is also the only
interface parameter that can be changed when a circuit is connected.
