D-122 Data Uniform Numbering Plan - PRI
D-122 Data Uniform Numbering Plan - PRI
General Description
This feature enables data stations to be assigned a set of UNIFORM NUMBERS to distinguish data extensions from
voice extensions.
Data Uniform Numbering Plan Connection
Operating Procedure
Originating a Data Adapter/Data Module call using Uniform Numbering
1. Dial the private line access code (usually 8).
2. Dial the interoffice number (location code uniform number) and the desired DTE number; RDX
(interoffice number) - XXXX (desired DTE number).
3. When the called DTE answers, data communication can begin.
Originating a Data Adapter/Data Module call using Inter-Office Coordinate Numbering Plan
1. Dial the interoffice number (location code uniform number).
2. Dial the desired DTE number.
3. When the called DTE answers, data communication can begin.
Service Conditions
1. Careful consideration should be given to numbering plan assignments, especially in larger systems, to
avoid unnecessary loss of access codes or duplication of telephone numbers.
2. There is no limit to the number of groups assigned per system.
3. Telephone numbers cannot be duplicated between tenants.
4. Data extensions must contain from two to five digits.
5. Flexible data telephone numbering can also be used; however, its use is not recommended.
6. When an access code, an office termination code, and an interoffice data extension are dialed, the access
code and the first digit of the office termination code cannot be the same. For example, if 8-RNX-XXXX
is dialed to access an interoffice DTE; R cannot equal 8, N can equal 2 - 9, and X can equal 0 - 9.
7. KEYBOARD DIALING [K-1, K-2] can be used in conjunction with this feature.
8. Data calls over Tie lines require the use of modem pooling.
