splitter, you must connect the unit to a separate POTS splitter.
To cable the DSL Ports:
Procedure
1. Insert a cable tie (provided) through the top of the anchor mount next to the
ADSL2+ connector.
2. If 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:
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. Transceivers
are available from Paradyne. 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:
Procedure
1. Connect 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).
— 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.

3. Cabling
— 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.

2. Connect 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 MIM2000, 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.
