Mandatory. V.25ter section 6.3.5. All result codes are not in V.25ter. Before one of the above
codes is issued, the terminal may return some of the following codes:
+CR
,
+ER
,
+DR
, or
+ILRR
(in that order). In GPRS connections the data rate can actually be higher than the
value returned because it is the minimum desired value. The only verbose code returned in
the case of a GPRS call is the word CONNECT.
