NMS

LAN A

Router

The 7112 T1 DSU/CSU provides an interface between the T1 digital network and the customer premises equipment, converting signals received from the DTE (Data Terminal Equipment) to bipolar signals that can be transmitted over T1 lines.

The T1 DSU/CSU offers these features:

 10BaseT Port. Allows the DSU/CSU to connect directly to an Ethernet LAN.  SNMP (Simple Network Management Protocol) Management. Provides

network management via an industry-standard SNMP management system.

About the T1 DSU/CSU

 Management. Provides management via:

— ASCII terminal connection through the Terminal port — External modem through the Terminal port — Telnet through the Ethernet port or the FDL — SNMP through Ethernet port or the FDL

 Alarm Indication. Activates front panel LEDs.  Diagnostics. Provides the capability to diagnose device and network

problems and perform tests, including digital loopbacks, pattern tests, and self-test.

 Device and Test Monitoring. Provides the capability of tracking and

evaluating the unit’s operation, including health and status, and error-rate monitoring.

 Security. Provides multiple levels of security, which deters unauthorized

access to the DSU/CSU.

Using the ASCII Terminal Interface (ATI)

Accessing the ATI

You can communicate with the ATI using one of the following methods:

 Direct connection through the Terminal port.  Dialing in through an external modem to the Terminal port.  Telnet session through the Ethernet port.  Telnet session through the Facility Data Link (FDL).

NOTE:

Only one ATI session can be active at a time, and another user’s session cannot be forced to end. To automatically log out a user due to inactivity, enable the Inactivity Timeout option (see Table A-6, Terminal Port Options and Table A-7, Telnet Session Options).

The user interface is blank until activated. Press Enter to activate the user interface. Security can limit ATI access several ways. To setup security or a login ID, refer to Chapter 4,

Security

Connecting to the Terminal Port

Ensure that the device you connect communicates using the following settings:

 Data rate set to 9.6 kbps.  Character length set to 8.  Parity set to None.  Stop Bits set to 1.

To change Terminal port settings, refer to Table A-6, Terminal Port Options.

Displaying DS0 Channel Assignments

Use the Cross Connect Assignments screen to view which DS0 channels are currently assigned to the data port. Below each DS0 channel you will see either “Available” or “P”. DS0s with a “P” designation are assigned to the data port. DS0s marked “Available” are unused (unassigned).

Cross Connect Assignments may also be displayed by accessing the Cross Connect Status screen under the Status branch of the Main Menu.

Using the Block or ACAMI Assignment Method

By using the block or ACAMI (Alternate Channel Alternate Mark Inversion) assignment method, you can assign a data port to a block of contiguous DS0 channels on the network interface.

The block assignment method allows a block of contiguous channels to be assigned by specifying the number of DS0’s to allocate and an initial DS0 channel (the first DS0 channel in a block of DS0 channels). The number of channels assigned is determined by the port rate. These channels are automatically assigned to the destination network interface when the initial DS0 channel is selected.

Configuring the DSU/CSU

The ACAMI assignment method also allows a block of contiguous channels to be assigned. However, with ACAMI, the number of channels assigned is twice the number needed for the port rate. This is because with ACAMI, every alternate

DS0 channel (starting with the port, but instead always transmits and receives all ones.

Using the Individual Channel Assignment Method

This channel method allows you to select the individual DS0 channels to allocate to the data port. The data port rate is automatically determined based on the number of channels selected. The DS0s do not need to be contiguous.

 Procedure

To assign the data port by the individual channel method:

1. Access the Cross Connect Assignments screen by following this menu

selection sequence:

Main Menu→Configuration→Load Configuration From Cross Connect

2. Use the Assign By field to specify the assignment method (Channel).

3. Specify the port assignments for the individual DS0 channels. The DS0

channels do not need to be contiguous.

4. The port rate increases as the port is assigned to each additional DS0

channel. For example, if two DS0 channels (at 64 kbps each) are assigned to the data port, a port rate of 128 kbps is required.
