S16

This S-register stores test function status in a bit-mapped format as follows:

bit 0 — local digital loop test; 0 = test disabled, 1 = test in progress (default = 0, see the &T1 and &T2 commands)

bit 1 — not used (always set to 0)

bit 2 — local data loop test; 0 = disabled, 1 = test in progress (default = 0, see &T3 command)

bit 3 — status bit for remote digital loop initiated by remote system; 0 = off, 1 = in progress (default = 0, see &T4 and &T5 commands)

bit 4 — remote digital loop; 0 = disabled, 1 = in progress (default = 0, see &T6 command)

bit 5 — remote digital loop with self-test 0 = disabled, 1 = in progress (default = 0, see &T7 command)

bit 6 — local digital loop with self-test; 0 = disabled, 1 = in progress (default = 0, see &T8 command)

bit 7 — not used (always set to 0)

Value may be 00 to FF hexadecimal; factory-default settings produce a value of 00 (see comment 1).

no

1 . Only one of the tests may be in progress at any time. The T0 command terminates any locally initiated test in progress and sets S-register 16 to 00.

2 . Refer to the explanation of hexadecimal values under the Range of Values label description at the beginning of this appendix.

Chapter 4, “Operation and Configuration”; refer to the indicated AT command in Appendix A, “AT Command Set.”
