Chapter 6      Conversions and Transparency

  Advanced Service Interworking

When the Q.931 QSIG protocol profile is selected, the QSIG facility element encoding defaults to ETSI 
1995.

To change the facility coding definition manually, you must make changes in two windows as follows:

Step 1

Go to 

Configuration

 / 

Q.931 Services

.

Step 2

Set 

Facility Element Coding Standard

 to 

ISO 

(ISO 1994), 

ETSI 

(ETSI = ETSI 1995), or 

ECMA

 

(ECMA = ETSI 1993), and click 

SUBMIT

.

Step 3

Go to 

Configuration

 / 

Inter-Working

.

Step 4

Set 

Facility Element coding

 to 

ISO

 if you need either the ISO 1994 or the ETSI 1995 definition, or 

ETSI

 for the ECMA 1993 definition, and click 

SUBMIT

.

Note

Beware the discrepancy between meanings of the 

ETSI

 selection in the two different windows.

Cisco Systems, Inc., suggests that you contact your Q.931 equipment supplier if one or more 
Supplementary services will not interoperate with its default ETSI (1995) encoding and you suspect the 
Q.931 equipment may be operating to an alternative standard. With some PBX equipment, more service 
capabilities are available with the PBX configured for ECMA (1993) rather than ISO operation. 

QSIG Diversion Restriction

Certain DPNSS PBXs enforce an arbitrary constraint that prohibits a network user from diverting the 
phone to an off-net number (for example, a national mobile number). In a mixed network that includes 
such PBXs, the feature permits those QSIG PBXs that are capable of performing “call forward by join” 
to offer off-net diversion without the diversion request being referred back to and rejected by the DPNSS 
PBX.

In DPNSS, on determining that a call is being attempted to a phone against which a diversion is 
registered, the destination PBX signals this to the originating PBX. It should then attempt a new call to 
the “divert to” number that is identified by the destination PBX. Certain DPNSS PBXs enforce an 
arbitrary limit on the length of the “divert to” number. If it exceeds that length, the PBX will not attempt 
to divert the call, and the call fails. 

This can be controlled by setting 

Reject Diversion Request for Numbers Longer than

.

Some QSIG PBXs overcome this restriction, without requiring action from the originating DPNSS PBX, 
by making the diverting leg of the call and joining the new and original call legs. Cisco VG30D Voice 
Gateway can now get set up to detect the condition (overlong divert-to-number) and change its signalling 
to trigger the QSIG PBX to take alternative diversion action. Where the length of the divert to number 
is not excessive, Cisco VG30D Voice Gateway units allow the QSIG diversion request to “interwork” 
with the DPNSS PBX as normal.

 

After it is configured, the diversion interception action acts entirely 

automatically, and you can only turn it off by reconfiguring the option.

Using Diversion Restriction

The diversion restriction problem has been encountered specifically in networks that contain Ericsson 
MD110 PBXs that are using DPNSS signalling.
