V.35 Signal

Definition

21

Loop 2 Control

Signal initiated at local terminal and passed to local modem,

 

 

causing it to initiate remote digital loopback test (V.54 Loop 2).

22

Ring Indicator (RI)

Passed from local modem to local terminal. On during ringing,

 

 

off between rings and when no ring received.

23

External Transmit

Transmit timing signal generated by some synchronous DTEs,

 

Clock (B)

providing clock to the local modem.

24

External Transmit

Transmit timing signal generated by some synchronous DTEs,

 

Clock (A)

providing clock to the local modem.

25

Test Indicate (TI)

Local modem signals to local terminal when local modem is in

 

 

test. The terminal can initiate a Busy Out condition on this

 

 

circuit.
