CHANNEL 1 configuration detail
-
INTERFACE: lets you select the communications interface from among the ones
available by default in the unit: Net 1 (IP), Net 2 (IP), V35, ISDN1_L1, ISDN1_L2. Una
de las posiciones del selector está inactiva y aparecerá la indicación “NO INTERFACE”.
Selection options associated with the communication interfaces
In the case of ISDN interfaces, the two B channels that comprise them are displayed
separately as L1 and L2 for communications at 64Kbps or ISDN1_L1/L2 for
communications at 128Kbps (as shown in the previous image).
-
CODING / CODING (List): enables you to select the encoding algorithm associated
with this communication channel. Depending on the communication interface selected,
certain encoding modes may not be available.
List of algorithms
In the case of a SIP type communication over Net 1 or Net 2 interface, the isolated
encoding concept is replaced by the encoding profile concept, that is, an encoding list to
be negotiated between the units at both ends during the SIP phase of signaling, so
instead of specific encoding modes you choose modes groups (profiles) that are
created separately. For further information, consult section “3.1.10. SIP CODECS
PROFILES menu“ of this manual.
-
AUDIO IN SOURCE: allows you to select the source of audio of the communications
channel: ANALOG input(s) or DIGITAL input.
Audio input configuration options
-
BACK UP: this submenu enables you to configure the switching from the currently
selected communication interface toward a redundant communication interface in case
of connection failure. For a detailed description of this submenu, see section 3.1.6.1 of
this manual.
