1. Purpose

This Bellcore Practice (BR) describes the COMMON LANGUAGE standard codesthat identify Central Office (CO) circuit switching systems and packet switchingsystems. These codes are presented in both standard format and StandardTrunking and Transmission (STAT) format.

2. scope

This BR is applicable to circuit administration, provisioning, design, engineering,and other personnel having responsibility for designing, planning and/or servicingcentral office switching equipment. This BR applies primarily to organizationswith the following responsibilities:

. Distribution Services.

. Switching Operations.● Network Distributions.

The codes in STAT format are particularly applicable to the Circuit Design Sys-tem (C-1/CDS) and the Message Design System (C!-I/MDS) subsystems. The useof STAT codes in these two processes is described in BR 756-554-012, “C-l/CDSSystem Description, ” and BR 756-554-013, “C-1/MDS System Description. ”

3. GeneralDirect questions concerning this BR through the appropriate Bellcore customerCOMMON LANGUAGE code contact to the Language Standards Department,BeIlcore, General Codes Chairperson.

The Bellcore Language Standards Department provides the technical expertise tomaintain the General Code Set. The COMMON LANGUAGE TechnicalAdvisory Group contributes to this process, in accordance with the proceduresoutlined in BR 751-100-102, “COMMON LANGUAGE@ Abbreviation and CodeRequest Procedures. W

The standard business names for these codes are:. Central Office Switching Codes.● Packet Switching Codes.● Standard Trunklng and Transmission Switching System Codes.

This BR supersedes and cancels the following three BRs:● BR 751-100-445, “COMMON LANGUAGE@ Circuit Switching System

Codes–Central Office. n● BR 751-100-450, “COMMON LANGUAGE@ Packet Switching System

Codes–Central Office. n● BR 751-100-455, “COMMON LANGUAGE@ Standard Trunking and

Transmission (STAT) Switching System Codes. n

4. Reason For IssueThis BR is reissued to include new switching system codes assigned since the last Iissue and to administer general cleanup of Issue 2. Three (3) new tables have Ibeen added to this issue: Tables B, C and E; Table D in this issue was Table B in I

......=...:..

the previous issue. Table A is presented differently in this issue: the data was Ishown in CO, STAT, PKT order; in this issuej as a result of client requests> the Iorder is CO, PKT, STAT. Changes to data items that were in the last issue are Imarked with a (I) in the right margin. New codes are marked with a (t) in the Iright margin.

5. Circuit Switching System Codes—-Central OfficeThe Circuit Switching System Codes–Central Office uniquely identify all CentralOffice Circuit Switching Systems used in an exchange carrier environment. Thesecodes describe only Central Office Circuit Switching Systems. For other types ofswitching systems, refer to BR 751-100-440, “COMMON LANGUAGE* Switch-ing System Codes Description, Private Branch Exchange (PBW~ Centrex! andSpecial Services.”

A Central Office Circuit Switching System is a circuit switching entity. Itincludes the system control installed in a telecommunications system providingservice to the general public. It also has the necessary equipment and operatingarrangements for terminating and interconnecting lines and trunks.

The Circuit Switching System Codes–Central office are 2- and 3-characteralphanumeric codes.

6. Packet Switching CodesA Packet Switching system switches data received from a customer within apacket, bit-protocol format. A packet switching system must receive and deliverdata to the customer in this format. Vendor systems that can communicate withtheir components by means of a proprietary protocol, but cannot receive packetsfrom a customer, are not considered packet switches. A Packet switching ‘yStemdesignation is based on the packet-access capability of the customer rather thanon internal protocols or techniques.

Packet switching systems that support virtual circuit connections must also sup-port public dialing capability, as defined by the CCITT (International Telegraph

and Telephone Consultative Committee) Recommendation X.121.

The Packet Switching Codes are 2- and 3-character alphanumeric codes. Table Acontains the COMMON LANGUAGE codes for Packet Switching Systems.

7. Standard “flunking and Transmission (STAT) Codes

In addition to standard identification of Central Office switching systems andpacket switching systems described in paragraphs 5 & 6, the Bellcore TIRKS@system process requires additional trunking and/or transmission intelligenceinherent to a particular switching system. This need is met by the STAT codes.The use of the STAT codes in the CDS and MDS system processes is described inBR 756-554-013, “C-1/MDS System Description. ”

The Table System (TTS) contains the STAT Validation Table which, in additionto listing all available STAT switching system codes, contains the office range andimpedance values associated with each code. The initial STAT code values in theSTAT Validation Table are input by developers, but the table is open to eachoperating company to make changes to office range or impedance values only.This table is used to enable pass back of the default values of office range orimpedance to the ‘L OCREFDD” table, when new switching machine CLLITMcodes are created. For a description of the STAT Validation Table, refer to BR756-551-795, “TIRKS@ Reference Data Encyclopedia. ”

The STAT codes contain 4 characters. The first 3 characters are the same as the3-character standard switch code. When the standard switch code is two charac-ters, the third character of the STAT code is “-”. The fourth character is deter-mined by one of the following conditions:

. L = Local

● T = Toll

● * = Local and Toll, with the following exceptions:

— DMH* is Local

. DM2* is Toll.

● - = Not defined specifically as local or toll

8. TablesTable A, MCentral Office Switching System and Packet Switching Codes, ” con-tains the full name of the switches being encoded, along with a cross-reference tothe COMMON LANGUAGE Switching System Codes, the STAT codes, and thePacket Switching codes. The table is sorted by Manufacturer/Product.
