ABSTRACT: Issue 2 of GR-1193, LSSGR: Generic Requirements for a Dedicated Data Link Interface Between an End Office SPCS and CPE (FSD-04-07-000), replaces Issue 1.

GR-1193 describes the Telcordia view of proposed generic requirements for a dedicated data link that connects an end office Stored Program Control System (SPCS) with a Customer Premises Equipment (CPE). This link delivers to the end users useful information on their incoming calls without using the voice path for data transmission. Therefore, the customer's voice conversation will not be interrupted. In addition, data transmission will be possible in both the off-hook and on-hook states, and transmissions will be full duplex, i.e., in both directions. The modem at the SPCS will support transmission at speeds of 28800 bps and lower. It is recommended that this link be designed so it may be upgraded to support transmission at higher transmission speeds in the future.

Issue 2 of GR-1193 was updated to provide for higher modem speeds previously unspecified in the requirements. The requirements and text have been updated to reflect support for modem speeds up to and including the v.34 28800 bps ITU-T Standard.

GR-1193 replaced TR-NWT-001193 and TA-TSY-000034.

When using GR-1193, you may need to refer to GR-1188 and certain ITU-T recommendations. You may also want to refer to GR-512.
