Quick Configuration Guide (QCG)
TA 900/900e E&M Wink Trunk Quick Start Guide
Overview
This Configuration Guide explains how to configure a T1 port on the Total Access
900/900e for a Robbed Bit Signaling T1 to be connected to a PBX or other CPE
device that requires an E&M WInk connection.
Requirements & Limitations
In the TA 900 series, only T1 port 0/2 can be used for an E&M Wink connection.
In the TA 900e series, T1 ports 0/3 and 0/4 can be used for E&M Wink
connections.
Web Interface Configuration
Configuring the Local Dialing Type
First, we must set the Local Dialing Type to 7 or 10 digits. To do this, begin by
clicking on ‘Dial Plan’ under ‘Voice’.
Then, select the appropriate 7 or 10 Digit Dialing for local calls and click on
‘Apply’.
Configuring the T1 Interface

To begin configuring the T1 interface, click on ‘Physical Interfaces’ under
‘System’.
Next, click on ‘t1 0/2’ under the ‘Physical Interfaces’ list.
This will take you to the ‘T1 0/2’ Interface Configuration page. In the Description
box, you have the option of entering a label for the interface.
Next, you will want to check the ‘Enable’ box to enable the interface.
Click ‘Apply’ to apply the configuration above.
Since this will be an RBS interface, we want to reserve the T1 0/2 interface for an
RBS trunk by selecting ‘Reserve for RBS Trunks’ in the drop-down menu.
Specify the appropriate DS0 range using the drop-down boxes. When finished,
click the ‘Add’ button.
Note: This will create a specific TDM group for each DSO selected in the range.
If this is not the desired behavior, changes will need to be made via the

Command Line Interface. Go to the section titled ‘Configuring the T1 Interface’
under the ‘Command Line Interface Configuration’ for more information.
Configuring the RBS Trunk
First, we will configure a Codec List to be used by the RBS trunk. To do this,
click on ‘Codec Lists’ under ‘Voice’.
Click on the ‘Add New Codec List’ button to create a new Codec List.
Specify a name for the Codec List in the ‘Codec List Name’ field.
Specify the primary Codec to be used as ‘Codec #1’ and the secondary Codec to
be used as ‘Codec #2’. Once those are configured, click on ‘Apply’.

Next, we need to create the RBS trunk. To do this, start by clicking on ‘Trunk
Accounts’ under the ‘Voice’ tab.
Give the Trunk a name if you’d like.
Make sure that ‘Type’ is set to T1-RBS.
As of the current revision, the ‘Supervision’ can only be set to ‘E&M Wink’ and
the ‘Role’ can only be set to ‘Network’. When finished, click on ‘Add’.
You can specify an optional trunk description in the ‘Trunk Name’ field.
You will probably want to un-check the ‘Reject External’ box to allow trunk-to-
trunk calls to work properly. Un-checking this box allows the RBS trunk to accept
calls from other trunks that may be configured (i.e. PRI or SIP). This command is
necessary for deployments where more than one trunk is being used (i.e. a SIP
trunk and an RBS trunk to the CPE).

If DTMF digits are needing to be sent to the CPE when an inbound call is made,
Direct Inward Dialing will need to be configured by checking the DID box.
If Direct Inward Dialing is enabled, you need to specify the number of digits to be
sent to the CPE on an inbound call.
The way that a DS0 is allocated for a call can be configured to be ‘Linear’ or
‘Circular’. With ‘Linear’ the lowest available DS0 is used. With ‘Circular’, the
next DS0 in line is used.
To assign DS0s to the RBS trunk, begin by clicking on the ‘Assign DS0s’ button.
This will bring up a new window where particular DS0s can be added to the RBS
Trunk. In this example, we want to connect all 24 DS0s to the trunk so we select
all of the T1 0/2 DS0s by clicking on the check box under the ‘Add’ column for
each one. When finished, click the ‘Add DS0s’ button.
Click ‘Apply’ to apply the configuration changes.

The last step is to create a trunk group for the RBS trunk. To start this process,
click on ‘Trunk Groups’ under the ‘Voice’ tab.
Give the Trunk Group an appropriate name using the ‘Group Name’ field and
then click ‘Add’.
You can give the Trunk Group a description to help keep track of the
configuration.
To add the RBS trunk to the trunk group, click on the ‘Add Members’ button.
A new window will open with the available trunk accounts. Check the box under
the ‘Add?’ column for the appropriate trunk account and then click on the ‘Add
Selected Trunks’ button.

To configure calls to certain numbers to route out of the RBS trunk, click on the
‘Configure Advanced Templates’ button under the Call Templates section.
A good rule of thumb is to be specific with trunks going to CPE devices and be
general when creating call routing rules with trunks going to the PSTN/SIP
network. In this example, we have been assigned the number 256-555-1000 by
the SIP provider and want to route that number out the RBS trunk. To do this,
add the specific number to the ‘Template’ box and assign a ‘Cost’ of 0. When
finished, click on ‘Add’.
Once the Permit Template(s) have been verified, click on the ‘Return to Trunk
Group Config’ button.

Click on the ‘Apply’ button to apply the configuration changes.
Always remember to save your changes by clicking on ‘Save’ at the top of the
Web GUI.
Command Line Interface Configuration
An RBS trunk is configured over a T1 interface. To begin, we must setup the T1
interface correctly and then connect it to the RBS trunk.
Note: The configuration parameters used in the examples are for instructional
purposes only. Please replace all underlined entries (i.e. example) with your
specific parameters to configure your application.
Configuring the T1 Interface
First, you must create a TDM group. The following example creates a TDM
group of 24 DS0s (Channels 1-24 at 64kbps each) on the T1 connection.
Note: The Web Configuration will create 24 individual TDM groups each
comprised of one DS0. This is necessary if a particular DID needs to go to a
particular channel on the RBS Trunk (Multiple voice trunk accounts and trunk
groups are needed for this functionality). If this is not necessary and any DID
can go down any channel, only one TDM group is needed when configuring via
the CLI (This situation is used for the Web Configuration and the Command Line
Interface Configuration in this guide).
(config)#interface t1 0/2
(config-t1 0/2)#description RBS T1 to PBX

(config-t1 0/2)#tdm-group 1 timeslots 1-24 speed 64
(config-t1 0/2)#no shutdown
(config-t1 0/2)#exit
Configuring the RBS Trunk
Step 1:
First, it is a good idea to create an appropriate Codec List to be used by the PRI
trunk. In a Codec List, you can specify which codec should be prioritized by the
trunk when negotiating the call setup. In this example, a Codec List named
‘Trunk’ is going to be configured to use G.729 as the primary codec and G.711
as the secondary codec.
(config)#voice codec-list Trunk
(config-codec)#codec g729
(config-codec)#codec g711ulaw
(config-codec)#exit
Step 2:
Next, create the RBS voice trunk using the ‘voice trunk’ command and specifying
the type as ‘t1-rbs supervision wink role network’. An optional description can be
given to the trunk as well using the ‘description’ command. The command ‘no
reject-external’ allows the RBS trunk to accept calls from other trunks that may
be configured (i.e. PRI or SIP). This command is necessary for deployments
where more than one trunk is being used (i.e. a SIP trunk and a PRI/RBS trunk to
the CPE). Finally, connect the voice trunk to a TDM group on a T1 interface
using the ‘connect’ statement. The ‘did digits-transferred’ command specifies
how many DNIS digits will be sent to the CPE device on an inbound call.
(config)# voice trunk T02 type t1-rbs supervision wink role network
(config-T02)#description "RBS T1 to PBX"
(config-T02)#no reject-external
(config-T02)#connect t1 0/2 tdm-group 1
(config-T02)#did digits-transferred 10
Step 3:
Since this is a voice trunk and not a voice user, a voice grouped trunk will need
to be configured to specify which numbers should be routed out the RBS trunk.
A good rule of thumb is to be specific with trunks going to CPE devices and be
general when creating call routing rules with trunks going to the PSTN/SIP
network. In this example, we have been assigned the number 256-555-1000 by
the SIP provider and want to route that number out the RBS trunk. We do this by
adding an ‘accept’ entry for the specific number.

(config)#voice grouped-trunk "RBS T1 TO PBX"
(config-RBS T1 TO PBX)#trunk T02
(config-RBS T1 TO PBX)#accept 256-555-1000 cost 0
Step 4:
Once everything is configured correctly, you will want to save your changes.
(config)#exit
#copy running-config startup-config
