n Cabling
Use only CAT3 or better twisted-pair network connection cables for DSL
Termination Unit connections and interface patch cabling. Untwisted analog
cables of any length anywhere in the loop substantially contribute to crosstalk
and reduced loop reach.
The following customer-provided cables and cable adapters are required with
this product:
— Plug-ended Telco 50-pin cable for connection from the Hotwire 8620
GranDSLAM Line ports to the CO POTS splitter shelf or MDF, one cable
per DSL card.
— 8-pin UTP CAT5 modular cable for connection from the Hotwire 8620
GranDSLAM MANAGEMENT MCP port to a 10/100 BaseT hub connector
(connected to an SNMP management system network) for Slot 1 in the
base chassis. For TDM SDSL and TDM SHDSL cards, refer to the
appropriate card Installation Instructions for the correct cable needed.
— A 14-foot serial cable and DB25 and DB9 adapters are shipped with the
MCP card. For connection to a modem, you need a null modem adapter.
If there is limited work space behind the rack, install any rear-mounted
network connectors on the chassis before mounting the chassis in the rack.
CAUTION:
Use of any nontwisted pair wiring arrangements, such as jumpers, can
cause a reduction in overall DSL reach performance, even over short
distances.
NOTE:
The Hotwire 8620 GranDSLAM chassis weighs 15 to 18 pounds (depending
on model) and can be easily installed by one installer.
