V.120 Configuration Commands

AT!E5=n	V.120 N200 (Maximum Retry Count). Applicable to the multiframe mode only. N200
	(Maximum Retry Count) is a system parameter which identifies the maximum number
	of retransmissions of a frame due to T200 expiring. When the maximum number of
	retransmissions is reached, the recovery process is started which may cause call
	disconnection.
	Range: 1 to 10.
	Default: 3.

AT!E6=n	V.120 T203 (Link Integrity Timer). Applicable to the multiframe mode only. T203 (Link
	Integrity Timer) is the maximum time allowed without frames (including data and
	control) being exchanged. Its purpose is to verify that the remote device is still online
	and operational. When the Link Integrity Timer expires, recovery procedures are started
	which may cause the disconnection of the current call.
	The unit of measurement is seconds.
	Range: 1 to 255.
	Default: 30.
	The value specified for T200 (Retransmission Timer) (see “AT!E4=n” on page 42) must
	be less than the value specified for T203 (Link Integrity Timer). Otherwise, the default
	values are used.

AT!E7=n	V.120 Idle Timer. Idle Timer refers to the maximum time without the exchange of data
	frames between the local and the remote devices and before the automatic termination
	of the connection. Its purpose is to reduce communications costs while data is not
	being transferred for a period of time (operates in both the multiframe and
	unacknowledgement modes). When Idle Timer expires, this immediately initiates the
	disconnection of calls. Setting a zero value disables Idle Timer.
	The unit of measurement is minutes.
	Range: 0 to 10000.
	Default: 1440 (24 hours).
