UDP conversion is specified for individual extensions or groups of extensions sharing 
the same leading digits, via the UDP form and extension codes. An extension code is 
the desired leading digits of an extension followed by an “x” (wildcard). For example, 
“123xx” “12345”is the extension code for all 100 possible extensions beginning with 
“123” plus two...

A given station is called using the same 5-digit extension regardless of where in the 
ETN the call originates. Three switches are included in the example. Each has been 
assigned a list of RNX and UDP codes. See Figure 7.

If a user at extension 41000 wants to call extension 61234, there are two choices: 
•Dial 61234
•Dial the AAR access code followed by 222-1234
If 61234 is dialed, the system recognizes 61 as a remote UDP, determines the 
associated RNX (222), and uses AAR to route the call to 222-1234.
If the AAR access code and 222-1234 are dialed, the system finds the route...

•If AAR is active, FRLs and Traveling Class Marks (TCMs) can be sent along with 
the private network number. UDPCode and AARCode conversions use the FRL 
assigned to the caller. ENPNode conversion always raises the FRL to the 
maximum (7). 
If an FRL is insufficient to access the facility, access is denied. There is no prompt 
for an authorization code even if...

ISDN Feature Plus
This feature allows you to have basic feature transparency over public networks 
without having a dedicated leased line. This provides a lower cost option for using the 
switched public network.

Description
ISDN Feature Plus uses a DEFINITY ECS proprietary signaling protocol. The 
features do not function in the same way as their QSIG or DCS counterparts.
To use Feature Plus, Phase I, you need DID extensions. In addition to the general 
Feature Plus call handling, Feature Plus includes the following features:
•Centralized AUDIX — A simple, one step “coverage” to voice...

Interrogation
When performing an audit, the Served User PBX sends a request towards the 
Message Center PBX. As a Message Center PBX, the DEFINITY ECS receives the 
request message, maps it into a MW STATUS REQUEST - SINGLE STATION 
message, and sends it to AUDIX on the BX.25 link. When AUDIX replies to the 
DEFINITY on the BX.25 link with a MW STATUS UPDATE, the Message...

•Feature Plus Forwarding (Diversion)
~Calling Line Identification Presentation (CLIP)
If the public network supports CLIP and the forwarded-to user has subscribed 
to the service, then calling party information is available to the forwarded-to 
user’s display.
~Connection Line Identification Presentation (COLP)
If the public network supports COLP and the calling user has...

•Feature Plus Message Waiting Indication
~Audio Information Exchange (AUDIX)
Feature Plus MWI depends on the presence of a Message Center. Whenever 
DEFINITY ECS acts as a Message Center switch, there is an interaction 
between DEFINITY ECS and AUDIX. DEFINITY ECS must be able to 
receive messages from AUDIX then, if applicable, send the appropriate 
Feature Plus MWI message...

QSIG
QSIG is the generic name for a family of signaling protocols. The Q reference point 
or interface is the logical point where signaling is passed between two switches in a 
private network. QSIG signaling allows certain features to work in a single-vendor or 
multi-vendor network. QSIG complies with the International Organization for 
Standardization (ISO) Integrated Services Digital...
