 * DPNSS (Digital Private Network Signalling System) is a telephony network protocol for linking

 * Private Automatic Branch Exchanges (PBXs) over digital trunk lines, allowing shared advanced calling features

 * (like Call Forward, Caller ID, Call Transfer) across multiple sites as if on one system. Developed from BT's DASS,

 * it uses a separate data channel (D-channel, often Time Slot 16 on E1 links) for signaling,

 * enabling seamless voice services across different manufacturers' equipment within a private network.

 *

 * Key Aspects of DPNSS

 * Purpose: Extends single-PBX features (like extensions, voicemail integration) across interconnected PBXs in a private network.

 * Origin: Defined by British Telecom (BT) for private network interoperability.

 * Technology: Operates over digital circuits (like E1/T1) using ISDN interfaces, reserving specific time slots for signaling.

 * Interoperability: Allows equipment from different vendors (e.g., Mitel, Meridian) to communicate advanced services.

 * Services Supported: Includes call forwarding, caller ID, message waiting indication (MWI), and call transfer.

 * Standards: Defined in documents like BTNR188 and RFC 4129 for extensions.

 * How it Works

 * Signaling Channel: Uses a dedicated data channel (D-channel) within the digital link for control messages, separate from voice channels (B-channels).

 * Feature Negotiation: PBXs use the DPNSS protocol to signal and offer supplementary services to each other.

 * Network Configuration: Administrators set up trunk groups and routing to connect PBXs, creating a unified network.

 * DPNSS vs. QSIG

 * DPNSS is a private network protocol, while QSIG (Signalling System No. 7 based) is a more formal standard for public and private networks.

 * Gateways are often used to connect DPNSS networks to QSIG networks, with basic calls typically passing through, as shown in this Mitel documentation.

/* 3.1 Supplementary Information Strings

 * A Supplementary Information String comprises a Supplementary

 * Information Identifier which may be followed by one or more

 * Parameters. A Supplementary Information String starts with the

 * IA5 character * and ends with the IA5 character #.

 *

 *  When the Supplementary Information String includes Parameters

 * these are separated from the identifier and each other by a *.

 * eg * Supplementary Information Identifier code #

 * or * Supplementary Information Identifier code * Parameter #

 * or * Supplementary Information Identifier code * Parameter * Parameter #

 * A Supplementary Information String shall be wholly contained

 * within one Selection or Indication Field (ie it shall not be

 * split between messages).

 *

 * 3.2 Supplementary Information String Identifier

 * The identifier comprises one or more IA5 numerals 0-9 which may

 * be followed by a single IA5 alpha-character suffix in the range A-Z.

 * The numerals of the identifier indicate the main function of the

 * Supplementary Information String, eg "39F" indicates "Diverting

 * on No Reply". "F" is the suffix.

 *

 * 3.5 Destination Address

 * The Destination Address comprises one or more IA5 numerals 0 to

 * 9, has no identifier code and is not prefixed by a * or

 * terminated by a #. The digits are always the last characters in

 * the Selection Block. The first Destination Address digit

 * immediately follows the # of the last Supplementary Information

 * String.
