4.6. ISDN (ISDN1) communications interface configuration.
There is an ISDN interface installed into Phoenix STRATOS (ISDN1).
In order to establish an ISDN communication using CH1 or CH2, first we need to choose within
the “INTERFACE” drop-down menu of the desired channel one of the following options: “ISDN1
L1+L2 128k”, “ISDN1 L1 64k” or “ISDN1 L2 64k.
We can access the ISDN configuration submenu by clicking on “I/F Setup”. This menu is
described in section 6.1.4.4 of “AEQ ControlPHOENIX” user’s manual.
In this case, the type of physical interface will be selected (S or U), the ISDN protocol
(EuroISDN or National 1) and whether the TEI is dynamic or fixed. We will also indicate the
MSN numbers (SPID if protocol is National 1), whether we want automatic recall or not and its
timing.
4.7. Coding selection.
See section 6.1.3.1 (”Coding selection”) at “AEQ ControlPHOENIX” user’s manual.
By clicking on the ”Select
codec” button located inside
the “ENCODER” area of the
general configuration window,
you can access the coding
selection
screen.
In
this
window, with “INTERFACE” is
configured as V35, ISDN or IP
(set as ”RTP raw”), only the
modes that are compatible
with
the
communications
interface selected appear.
Note that the “DECODER” will
be automatically configured for
the same coding algorithm and
mode.
