QSig |
Definition |
| CorNet is usually the protocol used for networking HiPath systems with each other. QSig, the cross-vendor signaling protocol, is used for networking HiPath and non-HiPath systems. In homogeneous networks, HiPath 3000/5000 supports the following basic features. |
| In QSig environments, you can operate HiPath 3000/5000 as an end node, transit node, or gateway. |
| You can use the QSig protocols, which are based on the following specifications: |
| • | ECMA V1.0 and ECMA V2.0 (for the MWI feature only) with the partial specifications - ETS 300172: Basic Call / ECMA 143 - ETS 300239: Generic Functions / ECMA 165 |
| • | ISO partial specifications - ISO 11572: Basic Call, ID Identifications (CLIP, CLIR, COLP, COLR) - ISO 13868: Name Identification - ISO 13869: Call Transfer - ISO 13870: Call Completion (Call Completion Busy, Call Completion No Reply) - ISO 13873: Call Forward Unconditional - ISO 15506: Message Waiting Indication |
| These networked systems collectively act like a single system, transmitting the following over the S0 trunk: |
| • | Callback option |
| • | Station number |
| • | Name |
| • | Party category |
| • | Transit counter |
| Called parties with toll restriction "0" (no direct trunk access) for a QSig trunk cannot answer an incoming QSig call for another station (call pickup, trunk key). However, direct calls and forwarded calls to the B party are possible. |
| Interworking With Other Protocols |
| • | CorNet-N All existing features implemented for both CorNet-N and QSig support interworking in the QSig direction and vice versa. The only exceptions are the callback feature (CCBS/CCNR) and the message waiting indication (MWI) because the message flows between the two protocols and the ones between two nodes are too different. |
| • | ETSI The requirements for interworking between CorNet-N and ETSI apply here as well. |
Supported Features |
| • | Numbering plan |
| - | ISDN Numbering Plan |
| - | The system does not support a private numbering plan. |
| • | Call detail recording |
| - | In the local system: same as before. |
| - | Call charges are not transferred in transit traffic. |
| • | Direct inward dialing (external) |
| - | In the local system: same as before. |
| - | Direct inward dialing is not possible in transit traffic. |
| • | Consultation hold |
| - | In the local system: same as before. |
| - | In the remote system: Consultation calls over a second trunk are possible; that is, the call is switched over two B channels by the local system, and they can be transferred. When a user releases the call, the call last placed on hold becomes active. |
| • | Callback |
| - | Users can activate completion of calls - no reply (CCNR) or completion of calls to busy subscribers (CCBS) to the remote communications system. They can activate CCNR if the other party does not answer or if a call is waiting. They can activate CCBS in the following situations: The other party is busy with one or multiple calls, engaged in a consultation call or a conference, or has activated do not disturb. |
| - | Users cannot set a callback to a call forwarding destination, a member of a group call or hunt group, a room monitor, or an entrance telephone. |
| - | Callback calls are deleted when the CS is reset, a trunk fails, or a port is reprogrammed; AB and BA calls are also deleted. |
| • | Call forwarding |
| - | To optimize B channel usage a forwarded call is handled in accordance with the specifications for "call forwarding/partial rerouting". If partial rerouting is rejected, forward switching is used. |
| - | If the Hicom 150 E Office/HiPath 3000 is acting as a gateway, forward switching is performed (even where there are 2 QSIG trunk groups). |
| • | Name display |
| - | Only UPPERCASE letters are transferred. Users can specify whether a transferred name or the caller's station number should be displayed. |
Additional QSIG/QSIG+ Features |
| The generic term QSIG+ covers all features that are not standard QSIG features. |
| The following functions for a central Attendant position connected to an A6 communication system are supported based on QSIG features: |
| - | Call intercept (CINT) |
| - | Call intrusion (CI) |
| - | Recall (RE) |
Central Call Detail Recording using QSIG |
| If central call detail recording is activated via QSIG, unit-oriented CDR must continue to be set in the communication system. Central call detail recording via QSIG does not support call charge oriented CDR. |
