== Summary ==
This document explains how to configure LDAP directory reverse look-up for Ascom branded IP-DECT devices.

== Applies To ==
This information applies to

* Ascom branded IP-DECT devices.

== Configuration ==
The reverse look-up can not be configured with the GUI on Ascom branded IP-DECT devices, but with command lines. This are the available configuration options:
* /search-enable
* /search-server ''LDAP server IP address''
* /search-user ''LDAP server user''
* /search-pwd ''LDAP server password''
* /search-base ''LDAP server search base''
* /search-name-attrs ''LDAP server name attributes''
* /search-num-attrs ''LDAP server number attributes''
* /dl-cc ''country code''
* /dl-ac ''area code''
* /dl-ntp ''national prefix''
* /dl-itp ''international prefix''
* /dl-col ''external line''
* /dl-subscr ''subscriber numbers''

The ''config add'' command can be used to add the configuration options to the DECT Master module. Here is an example for the command, the configuration values must be substituted:

<code>!config add GW-DECT MASTER /search-enable /search-server 172.16.0.1 /search-user ldap-guest /search-pwd passwd /search-base cn%3Dpbx0 /search-name-attrs cn%2CgivenName%2Csn%2Ccompany /search-num-attrs e164 /dl-cc 49 /dl-ac 30 /dl-ntp 0 /dl-itp 00 /dl-col 0 /dl-subscr 223344</code>

<code>!config write</code>

<code>!config activate</code>

The configuration GUI for this feature can be accessed by entering following URL in the web browser:

Alessandro: /* QSIG D-channel protocol: */

In the '''Protocol''' submenu, you can set the protocol to be used for the ISDN interfaces. From the six available protocols, select the one that is best suited to your environment or if you have CAS enabled, select one of the three available:

== Euro ISDN D-channel protocol: ==
* '''EDSS1:''' This type of signalling has gained worldwide acceptance for ISDN subscribers and, despite the name, is also common outside Europe.

== QSIG D-channel protocol: ==
This is a standardised signalling method that is mainly used to connect PBXs. Here, basic call and tunnelling are supported by the gateways. This allows, in particular, homogeneous PBX systems to be linked with QSIG (1 byte), in which manufacturer-specific properties are exchanged via QSIG.
Unfortunately, there are several variants of the QSIG standard and various implementations; some conform more and some less to the standard.

The gateways therefore support two different variants.
* '''QSIG ECMA1:''' Numbering of the channels from 1-30 (2 bytes)
* '''QSIG ECMA2:''' Numbering of the channels from 1-15, 17-31 (2 bytes)

== NI D-channel protocol: ==
* '''NI:''' USA (National ISDN 1)
* '''5ESS:''' USA (AT&T)
* '''DMS100:''' USA (new standard)

== Mode: ==
If your trunk line is a point-to-point type, select Point-to-Point. If it is a point-to-multipoint connection, then select Point-to-Mulitpoint. This setting is irrelevant for permanent connections. If the connection is operated in mixed mode (one B channel permanently used for a fixed connection, one B channel in dial-up mode), the setting depends on the operating mode of the dial-up line (only TEL1-4 and PPP).
* '''Point-to-Point:''' Switches on the point-to-point connection.
* '''Point-to-Multipoint:''' Switches on the point-to-multipoint connection.

'''If CAS is selected under [[ Reference:Configuration/PRI/Physical | Configuration/PRI/Physical]], you have different options:'''

== CAS: ==
=== protocols: ===
* '''E1_R2D''': refers to the ITU-T standard Q.421-Q.422.
* '''E1_3BIT''': refers to an iranian standard, which is similar to E1_R2D
* '''T1_WINK_START''': refers to ANSI/TIA-464-C and works only with T1 (see [[ Reference:Configuration/PRI/Physical | Configuration/PRI/Physical]])
=== assign channels from top ===
channels will be assigned from top (first used channel 30 with E1 or 24 with T1).
=== channel bank mode ===
in the channelbank mode, each CAS channel is fixed assigned to a telephone number and is not dynamically assigned as in trunk scenarios. The CAS interface then is connected to a channelbank. E.g. telephone with number 1 calls to the CAS interface, channel 1 is taken for this call. If telephone with number 3 calls, channel 3 is taken and so on (this is normally done with maps in the routing table). In the incoming direction its similar. If a call comes in on channel 1, it is transferred to the telephone with number 1 (or via maps in the routing table).
