5.2 SDSL extension in XMP1
The SDSL extension in the XMP1 system includes the following modules:
• ISHDSL module (05HAT00070AAL)
• RPS-XMP1 remote power supply module (05HAT00071AAN)
• SHDSL repeater (05HBA00123AAD)
ISHDSL module
In the SDSL line equipment of the XMP1 system, the ISHDSL module
(05HAT00070AAL) provides four SDSL interfaces, four external E1
interfaces and four internal E1 interfaces to the XMP1 kernel.
RPS-XMP1 remote power supply module
The optional RPS-XMP1 remote power supply module (05HAT00071AAN)
provides four remote supply voltages of -116 V for powering the SHDSL
repeaters. The remote supply voltage is applied to the ISHDSL module via
its front cabling.
SHDSL repeater
In the SDSL link, the SHDSL repeater (05HBA00123AAD) designed in
compliance with ITU-T G.991.2 is used to regenerate the iSDSL signals. Up
to eight (8) SHDSL repeaters can be installed on one link.
The SHDSL repeaters can be powered by the RPS XMP1 remote power
supply module and/or a local power supply. SHDSL repeaters can be
installed either in underground tray sleeves or in the cable distributor
(way-side cabinet).
The following figure shows a typical application of the SDSL line equipment
in the XMP1 system.
