error in the data received on the data channel.
Circuit 111 — Data Signalling Rate Selector
Used to select one or two data signalling rates of a
dual-rate synchronous DCE, or to select one of the two
ranges of data signalling rates of a dual-range synchronous
DCE.
Circuit 112 - Data Signalling Rate Selector
Used to select one of the two data signalling rates or
ranges of rates in the DTE to coincide with the data
signalling rate or range of rates in use in a dual-rate
synchronous or dual-range asynchronous DCE.
Circuit 113 - Transmitter Signal Element Timing
Provides the DCE with signal element timing information.
Circuit 114 — Transmitter Signal Element Timing
Provides the DTE with signal element timing information.
Circuit 115 - Receiver Signal Element Timing
Provides the DTE with signal element timing information.
Circuit 116 - Select Standby
Used to select the normal or standby facilities such as
signal convertors and communication channels.
Circuit 117 - Standby Indicator
Indicates whether the DCE is conditioned in its standby mode
with the pre-determined facilities replaced by their
reserves.
Circuit 118 - Transmitted Backward Channel Data
Equivalent to circuit 103, except that it is used for data
received on the backward channel.
Circuit 120 - Transmit Backward Channel Line Signal
Equivalent to circuit 105, except that it is used to control
the backward channel transmit function of the DCE.
Circuit 121 - Backward Channel Ready
Equivalent to circuit 106, except that it is used to
