Connecting the ADSL2+ and POTS Connectors

Connecting the ADSL2+ and POTS Connectors

DSL connector supports the tip and ring connections of up to 24 DSL ports over a 50-position cable. A POTS (plain old telephone service) splitter connector is also provided in certain models. If your model does not contain an integrated POTS splitter, you must connect the unit to a separate POTS splitter.

To cable the DSL Ports:

1Insert a cable tie (provided) through the top of the anchor mount next to the ADSL2+ connector.

2If the connector for your cable has a short captive screw, attach the cable to the ADSL2+ connector and fasten it to the jack screw with its short captive screw.

Connecting the SFP Connector or the 10/100/1000 Connector

There are two Ethernet interfaces on the faceplate of the DSLAM, only one of which may be used at a time:

z

z

An 8-position modular jack providing support for 1000BaseT

A Small Form-Factor Pluggable (SFP) socket providing, with the appropriate transceiver installed, support for 1000BaseX and 1000BaseT. See Appendix B, Equipment List.

Either interface can be used as the uplink for a single DSLAM, or for the terminating unit in a stack of DSLAMs.

To use the SFP connector or 10/100/1000 connector:

1Connect the uplink cable to the DSLAM:

For a wire connection, plug the 8-position modular plug of your uplink cable into the 10/100/1000 modular jack. A straight-through cable can be used regardless of the destination interface, since the port automatically distinguishes between a Medium-Dependent Interface (MDI) and an MDI Crossover (MDIX).

Install the supplied small ferrite choke on the cable as close as possible to the jack. Use a cable tie to hold the choke in place.

Connecting DSLAMs to Each Other

For an SFP copper connection, plug your transceiver into the SFP socket. Plug the 8-position modular plug of your uplink cable into the SFP transceiver’s modular jack.

For an SFP fiber connection, plug your transceiver into the SFP socket. Plug the LC connector of your fiber optic uplink cable into the cable socket of the transceiver. Observing the minimum bend radius for your cable, fasten it with cable ties in such a way that it will not be kinked or snagged in the course of other cabling. If you do not know the specifications for your cable, maintain a radius of at least ten times the cable diameter.

2Connect the other end of the uplink cable to the uplink interface, such as an Ethernet switch.

Connecting DSLAMs to Each Other

Two or more DSLAMs can be daisy-chained together. All DSLAMs in this configuration must have a MIM installed; the MIM2000F, with two GigE ports, is recommended for performance reasons.

When daisy-chaining, one Ethernet port must be connected to the LAN, normally to a router. A second Ethernet port is connected to an Ethernet port of another 4900 DSLAM, or to the uplink interface.

The connection to the downstream DSLAM must be specified. This is done using the web interface. See DSLAM Interconnect Configuration in Chapter 5,

Configuration Using the NMS.
