Transport systems provide the means to transmit information between
designated interfaces in a communications network. They consist of hardware,
software, and media that combine, process, and transmit signals used to support
telecommunications services. GR-499 describes the Telcordia view of the basic
generic requirements common to transport systems.

The value of GR-499, Issue 4:

• One Key Resource - GR-499 serves as a repository for
  criteria covering a very broad range of topics of importance — significantly
  reducing the number of documents that need to be consulted when dealing with
  transport systems


• Continuity and Consistency - GR-499 provides continuity and
  consistent terms for use by multiple designers, suppliers, and
  manufacturers


• Network Compatibility and Economies of Scale - GR-499 helps
  ensure product and network compatibility, and promotes economies of scale for
  service providers


• Aligns with ATIS and ITU specifications - The impedance/return
  loss criteria for DS1, DS1A, DS1C, DS2, DS3, and SS4NA electrical interfaces now
  align with the specifications in ATIS-0600403 and ITU-T Rec. G.703.

When using GR-499, you may want to refer to GR-63, GR-78,
GR-253, GR-320, GR-357, GR-418, GR-454, GR-468,
GR-839, GR-1089, GR-1230, GR-1244, GR-1400 and
GR-2914, as well as other modules of the TSGR, OTGR and RQGR (FR-440,
FR-439 and FR-796) various standards documents.
