G.SHDSL Mini-Physical Interface Module Key Features
The G.SHDSL Mini-Physical Interface Module (Mini-PIM) provides the following key features:
- 2-wire (4-port 2-wire) mode, 4-wire (2-port 4-wire) mode, and 8-wire (1-port 8-wire) mode support
- Annex A, Annex B, Annex F, and Annex G support
- Virtual circuits per Mini-PIM (8 maximum)
- Asynchronous Transfer Mode (ATM)-over-G.SHDSL framing
- ATM class-of-service (CoS) support
- ATM Operation, Administration, and Maintenance (OAM) support
- Dying Gasp support
Dying Gasp is the ability of the device to automatically notify the service provider digital subscriber line access multiplexer (DSLAM) if a power failure occurs. The customer premises equipment (CPE) sends a message to the DSLAM, which identifies that a line was lost because of loss in CPE power.
- Wetting current support
Wetting current is a small amount of electrical current sent from the central office (CO) over the copper pair to the CPE to prevent the erosion of the copper wires. Some service providers also use wetting current as a method for identifying cable pairs, and they therefore need to recognize and receive wetting current. Additionally, wetting current can be used to power devices such as repeaters and low power devices.
- Noise margin support
- Point-to-Point Protocol over ATM and PPPoE over ATM encapsulation support
- Local loopback mode support
