DIAGNOSTICS
INTRODUCTION
The modem is supplied with circuits for diagnostics in compliance
with CCITT recommendations. They can be used to carry out a
complete test of all the elements making up the network.
The command used to enable the loops from DTE is &Tn; the list
below describes the function of this command and are only valid
in HAYES mode.
&T0 = Remove the active loop.
&T1 = The analog loop is enabled (loop3).
&T6 = Sends a request for a remote digital loop (loop 2).
N.B: The loop functions are only active for connections without
MNP or buffers.
Enabling Remote Loop 2
This loop can be enabled only with the modem in V.22 and
V.22bis with RDL (Remote Digital Loop) enabled.
With the two modems connected to each other, key in the
ESCAPE sequence and then "AT&T6" or else press the TEST
push-button on the front of the modem.
The data transmitted by the local DTE on the C103 are transmitted
on line, at the other end of the remote modem it will retransmit the
data, thus bringing them back to the local modem as C104.
