Connecting to the Telco Connectors

Because of the wiring differences between the DPA 7630 and 7610, you connect to the Octel and PBX systems slightly differently. Refer to the instructions for the specific model you are using in one of the following sections:

Connecting to the Octel and Definity Systems on a Cisco DPA 7630

Use the three telco connectors to connect the DPA 7630 to the Octel and Definity systems. Each telco connector connects to eight ports on the DPA 7630 (see Figure 2-6).


Figure 2-6: Connecting to the Telco Connectors on the DPA 7630


The pinouts on the telco connectors match those on a Definity four-wire line card (see Figure 2-7 for details) with the following characteristics:

  • Each port consists of 2 telco pairs

  • Each port is preceded by one unused pair; the first unused pair is wires 1 and 26


Figure 2-7: DPA 7630 Telco Connector Pinouts


Because the wiring matches the Definity PBX, you can easily connect the DPA 7630 to the Definity PBX via a punch panel. However, the wiring to the Octel system is more complicated because there are no unused pairs (see Figure 2-8 for details.)


Figure 2-8: DPA 7630 Wiring to Octel System


The telco connectors must connect to the patch panel or punchdown block in specific ways depending on the configuration you are using.

Simple Integration Mode

In the simple integration mode, you are integrating Cisco CallManager and Octel voice messaging systems. In this scenario, you must connect all 24 ports in Lines A, B, and C from the DPA 7630 to the Octel system.

Hybrid Integration Mode

If you want to connect Cisco CallManager, Octel voice messaging, and Definity PBX systems, you must use the hybrid integration mode. To use this configuration, all MWI lines for the Definity and Cisco CallManager phones must pass through the DPA 7630, following the guidelines described in the "Implementing the Hybrid Integration" section.

Connecting to the Octel and Meridian 1 Systems on a Cisco DPA 7610

Use the single telco connector to connect the DPA 7610 to the Octel and Meridian 1 systems. The telco connector connects to 24 ports on the DPA 7610 (see Figure 2-9).


Figure 2-9: Connecting to the Telco Connectors on the DPA 7610


The pinouts on the telco connectors match those on a Meridian 1 two-wire line card (see Figure 2-10 for details) with each port consisting of 1 telco pairs.


Figure 2-10: DPA 7610 Telco Connector Pinouts


Because the wiring matches the Meridian 1 PBX, you can easily connect the DPA 7610 to the Meridian 1 PBX via a punch panel. However, the wiring to the Octel system is more complicated and varies depending on the type of Octel system you are using. For an Octel 200/300 system, the wiring is identical to the DPA 7610 and Meridian 1 system. See Figure 2-11 for an example of wiring to an Octel 250/350 system.


Figure 2-11: DPA 7610 Wiring to Octel 250 System


The telco connectors must connect to the patch panel or punchdown block in specific ways depending on the configuration you are using.

Simple Integration Mode

In the simple integration mode, you are integrating Cisco CallManager and Octel voice messaging systems. In this scenario, you must connect all 24 ports in Lines A, B, and C from the DPA 7610 to the Octel system.

Hybrid Integration Mode

If you want to connect Cisco CallManager, Octel voice messaging, and Meridian 1 PBX systems, you must use the hybrid integration mode. To use this configuration, all MWI lines for the Cisco CallManager and Meridian 1 phones must pass through the DPA 7610, following the guidelines described in the "Implementing the Hybrid Integration" section.

Verifying Installation

After you complete installation of the DPA 7630/7610 and have connected power to it, connect a console terminal to observe its initial startup procedure. You can only observe these initial startup messages when connected to the console port. Initially, the device uses DHCP by default, but you can reconfigure this after startup.

The startup process proceeds as follows:

1. Loads boot loader software image and starts up the DPA 7630/7610.

2. Performs self tests on the hardware, indicating whether the component passed; for example:

Testing RAM......passed
Testing FLASH....passed
Testing EEPROM...passed
Testing Ethernet..passed

3. Pauses for 10 seconds, allowing you to perform the following tasks:

  • Initiate an FTP session to upgrade main software image before it loads, allowing recovery from a previous failed upgrade (see "Resolving an Incomplete Upgrade" section).

  • Press Esc on the console terminal to access the boot loader menu.

4. Loads the main software image and displays the main menu (see Figure 2-12):


Figure 2-12: DPA 7630/7610 Main Menu


If the main software menu displays successfully, you can begin configuring the device as described in "Configuring the DPA 7630/7610". If the menu does not display properly, verify your connections and follow suggestions in "Troubleshooting the DPA 7630/7610."
