ATM-over-SHDSL Overview
The symmetric high-speed digital subscriber line (SHDSL) Physical Interface Module (PIM) is available for J Series Services Routers. The PIM supports multi-rate, high-speed, symmetrical digital subscriber line technology for data transfer between a single customer premises equipment (CPE) subscriber and a central office (CO). Unlike ADSL, which was designed for delivering more bandwidth downstream than upstream, SHDSL is symmetrical and delivers a bandwidth of 2.3 Mbps in both directions. The SHDSL PIM has 2 ports and supports ATM-over-SHDSL mode only.
SHDSL is defined in the following specifications from the ITU and the Internet Engineering Task Force (IETF):
- ITU G.991.2, Single-pair High-speed Digital Subscriber Line (SHDSL) Transceiver
- ITU G.994.1, Handshake Procedures for Digital Subscriber Line (DSL) Transceivers
- ITU G.997.1, Physical Layer Management for Digital Subscriber Line (DSL) Transceivers
- RFC 3276, Definitions of Managed Objects for High Bit-Rate DSL - 2nd generation (HDSL2) and Single-Pair High-Speed Digital Subscriber Line (SHDSL) Lines
J Series routers with SHDSL Annex A or Annex B PIMs act as a primary WAN link. They use an ATM interface to send network traffic through a point-to-point connection to a DSL-access multiplexer (DSLAM). You can configure Point-to-Point Protocol over Ethernet (PPPoE) over ATM to connect through DSL lines. For more information about configuring PPPoE, see Configuring PPPoE.
ATM-over-SHDSL interfaces are not supported on J2300 Services Routers.
 | Note: You can configure J Series routers with SHDSL PIMs for connections through SHDSL only, not for direct ATM connections. |
