Plan numbers are administered on either the First Digit Table (on the Dial Plan
Record form) or the Second Digit Table. They also are not administered on the
Extended Trunk Access Call Screening Table. Extended Trunk Access helps you
make full use of automatic routing and Uniform Dial Plan.
Inter-PBX Attendant Service
Allows attendants for multiple locations to be concentrated at one location.
Incoming trunk calls to the unattended location, as well as attendant-seeking
calls, route over tie trunks to the main location.
Japanese National Private Networking Support
Provides support for Japanese private ISDN networks. The Japanese private
network ISDN protocol is different from the standard ISDN protocol. The switch
will now support extensions to the ISDN protocol for switches using the Japanese
country code.
Private Network Access
Allows calls to other systems in a private network. These calls do not use the
public network. They are routed over your dedicated facilities.
QSIG Basic
Provides compliance to the International Organization for Standardization (ISO)
ISDN-PRI private-networking specifications. QSIG is defined by ISO as the
worldwide standard for private networks.
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 peer
entities in a private network. QSIG signaling can provide feature transparency in a
single-vendor or multi-vendor environment.
The system provides QSIG Basic Call Setup with Number Identification and
Transit Counter.
Number Identification
Allows a switch to send and receive the calling number. Additional parameters
that control the display of the connected number are administered on the
Feature-Related System Parameters form. QSIG Number Identification displays
up to 15 digits for the calling and connected numbers across ISDN-PRI interfaces.
