Provisioning Non-SS7-Based POPs

Introduction

Provisioning for POPs that do not require SS7 signaling is relatively simple. The fundamentals of installing the interface hardware have already been covered in "Provisioning the Gatekeeper Core." Refer in particular to Establishing Gateways, taking care to select the appropriate Cisco hardware. Table 2-4 discusses the interface cards and signaling types they support.

This chapter presents the following topics:

• Provisioning References
  
  
• Configuration Examples
  
  

Caution   Always consult with your telecommunications service provider to determine the appropriate signaling parameters for your Cisco interfaces. Before configuring ISDN PRI on your Cisco router, you need to order a correctly provisioned ISDN PRI line from your telecommunications service provider.

Provisioning References

For background, references for provisioning signaling and other fundamentals are provided below for the Cisco routers that are used as GWs, as well as for the latest version of the Cisco IOS.

Tip Information related to provisioning a particular Cisco voice GW may be obsoleted by the most current release of Cisco IOS software.

For Routers

The following provides links to online provisioning references for the following GW types:

• Cisco 3600 Series
  
  
• Cisco AS5300
  
  
• Cisco AS5350 and Cisco AS5400
  
  

Cisco 3600 Series

To provision Cisco 3600 series GWs, refer to the following for these routers:

Configuration Examples

Configuration specifics are provided later in this section for the following basic signaling types:

• E1 R2
  
  
• PRI ETSI
  
  
• PRI NI2
  
  
• T1 CAS FGB
  
  
• T1 CAS FGD
  
  

The basic configurations are as provided in Configuring Gateway Interfaces to the PSTN.

Note   As of the time of this writing, documentation for Cisco IOS 12.2 is the most recent. Documentation for Release 12.2 is available at the following URL: http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/index.htm For a practical background to the following discussion, refer to Configuring ISDN PRI and Other Signaling on E1 and T1 Lines, at the following URL: http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/dialts_c/dtsprt3/dcdchant.htm

Configuration Fundamentals: Configuring T1 Signaling on a Cisco AS5300

The following is an example basic configuration of a T1 interface on a Cisco AS5300. The following steps do only the following:

1. define a T1 controller interface

2. Assign a DS0 group number to the T1 interface

3. Assign T1 timeslots (DS0 channels) to the T1 interface

4. Assign the signaling type to the T1 interface

Step 1   Enter terminal configuration mode and assign a controller ID for one T1 interface.

Step 2   Assign a DS0 group that represents the T1 interface. Here we choose 0.

Step 3   Assign DS0 channels 0 through 23 to the interface.

Step 4   Assign a signaling type to the DS0 channels (collectively). Note the options.

Here we choose E&M Feature Group B (wink start protocol), and choose MF (multifrequency) signal tones.

Signaling Types and Examples

The following examples (presented in alphabetical order) illustrate the key parameters required for the various signaling types.

E1 R2

PRI ETSI

PRI NI2

Note   The voice-port 2:D and voice-port 3:D, correspond to controller T1 2 and controller T1 3, respectively, since they are configured as PRI, and therefore the "D" activates the D-channel.

Note   Neither "interface Serial0:23" nor "interface Serial1:23" appear in this configuration, because the corresponding "controller T1 0" and "controller T1 1" are configured as T1s, and therefore do not correspond to a serialx:23 assignment.

T1 CAS FGB

Note   See Configuration Fundamentals: Configuring T1 Signaling on a Cisco AS5300, for a more detailed example.

T1 CAS FGD

Note   See Configuration Fundamentals: Configuring T1 Signaling on a Cisco AS5300, for a more detailed example (except for the different feature group).
