Data Options and Profiles
ADM and the remote endpoint) are trying to control the higher speed endpoint
simultaneously.
If the conditions in the above paragraph cannot be met, then Mode 3 or V.120
are the recommended data protocols.
When Match.speed is set to off, a Mode 2 call to another endpoint can only be
established if the other endpoint is running at the same speed. Other data
modes use bidirectional flow techniques to connect endpoints of dissimilar
speeds.
Min.timer (Minimum Delay Timer)
Option Values: on, off
Applicable Data Protocols: X.25, Mode 3, BV64I, and BV56I
Turning on this option optimizes packet data transmission initiated from either a
person typing or from a computer.
If characters received from the attached data equipment are separated in time by
more than approximately 10 milliseconds, then packets are transmitted to the
network without artificial delay. This is the case for a person typing.
If characters are received more closely spaced in time than as described above,
characters are assembled into packets. This may be the case of a computer
answering a data base query or transferring a file. In general, the size of the
packet equals the number of characters received prior to a gap in the reception
or a full packet, whichever is less. An exception to the above occurs when the
first packet after a gap is transmitted. This packet may contain fewer characters
(possibly only one character).
Interaction with Idle.timer: An Idle timer value greater than .05 seconds takes
precedence over the Min.timer.
Mode
Option Values: B2, BA, DX25, BV64U, BV64I, BV56U, BV56I
If this option is changed during an active data call, it will not take effect until the
next data call. Mode selects the preferred data protocol your ADM uses to
originate a data call. This option refers to data call origination only. Incoming
calls, in contrast, are always answered with the data protocol specified by the
compatible caller. Unless clearly identified as DX.25, DMI Mode 2, or DMI Mode
3, the ADM assumes V.120 on incoming calls.
The Mode option setting must be matched to the capabilities administered on
your ISDN telephone line and to that of the endpoint you are calling. To find out
which values of the Mode option you should select, contact your system
administrator. Data calls will not work unless your telephone line has been
administered for the data mode(s) you wish to use (that is, ISDN D-channel
