Connecting the Uplink Lines

To connect the SMD2000-24T to T1 service:

1.Configure the T1 uplinks.

No configuration is necessary for the SMD2000-24T to operate at default settings. However, if you wish to run uplinks at settings other than the SMD2000-24T defaults, configure the uplinks prior to connection. Parameter settings may be changed using the Command Line Interface (CLI), Simple Network Management Protocol (SNMP), or the web-based management system. T1 Uplink Parameter Defaults on page 15 lists the device defaults for the T1 uplinks. Product Documentation Online on page 3 lists the user interface manuals.

2.Plug your T1 cable into an RJ48C T1 uplink port on the SMD2000-24T faceplate. For most applications, a straight-through T1 cable is required. A connection to Port 2 is shown.

3.Connect to the remote T1 equipment. The SMD2000-24T requires only one uplink connection for operational purposes, although a second T1 uplink connection may be desired for redundancy. Additionally, the two T1 uplink ports may be bonded together for a single connection as long as the remote T1 equipment is loop bonding capable. Refer to Product to Product T1 Loop Bonding Compatibility, (Document Number COMP-A2-GK44) for a list of loop bonding capable products.

Using two T1 lines for one uplink connection nets twice the speed and data passing capability of a single-line T1 connection. Additionally, use of a second T1 line provides automatic backup should one of the lines experience problems or become disabled.

A single line T1 uplink connection may be established between T1 Port 1 or T1 Port 2 and any standard T1 provider equipment.

4.Verify Your Connections. The Port 1 Link (LK) LED flashing or pulsing green indicates that a T1 Port 1 uplink connection has been established. The Port 2 Link (LK) LED flashing or pulsing green indicates that a T1 Port 2 uplink connection has been established.
