3.2 ISDN interface: Selecting the ISDN connection
type
Depending on the particular usage, ECOTEL ® can be connected
to the ISDN PBX or the fixed network connection in various ways.
The following sections describe some typical variants. The tables
contain the following information:
– Jack indicates into which of the two jacks of an interface
you should plug the ISDN cable
– Activate Interface describes the setting of the control box
with the same name in the Gateway Configuration module,
page ISDN > ISDN Interface 1/2.
– The remaining settings can be made in the Basic
Configuration module.
The entries in the routing table (as shown here) are made in the
Routing Table module.
Note: ECOTEL® ISDN2-120 lite only has a single female
connector per BRI interface and the mode of this connector
has a fixed presetting:
- BRI 1: TE mode
- BRI 2: NT mode
The connection type (PTP or PTMP) can be userconfigured
as required.
Note: Some device types have only one single jack per BRI
interface instead of separate NT or TE jacks (e.g.
ECOTEL ® ISDN2-2, ECOTEL ® ISDN2-140 and
ECOTEL ® ISDN2-180). You will need to use this jack
- along with a crossed cable (white sign) in NT mode, or
- along with an uncrossed cable (black) in TE mode.
