UCM6510 - E1/T1/J1 Configuration Guide

  • Updated on September 29, 2022

The UCM6510 supports T1/E1/J1 digital trunk and data trunk. Digital trunk allows voice transmission in digital signal while data trunk is used for data transmission so that the device can connect to the Internet. On the UCM6510, the system administrator can configure both trunks allowing voice and data transmission at the same time by specifying the channels. This document introduces how to set up T1 trunk on the UCM6510 as a configuration sample.

Figure 1: Sample T1 Topology Using UCM6510

For more information about how to configure UCM6510, please refer to the UCM6510 user manual in www.grandstream.com/support.

Connecting T1 Port

The following figure shows the UCM6510 front view where you can see the T1/E1/J1 port.

Using UCM6510 as E1/T1/J1 Gateway

The UCM6510 supports E1/T1/J1 which are physical connection technology used in digital network. T1 is the North American standard, J1 is used in Japan, whereas E1 is the European standard. This offers the possibility of deploying the UCM6510 as Digital Trunk with a Traditional PBX with E1, T1 or J1 interface allowing the possibility for clients behind the legacy PBX to benefit from VoIP capabilities.

This document will guide users how to configure the UCM6510 to act as Digital Gateway including inbound and outbound rules to allow routing calls from and to VoIP through the Digital Trunk.

Figure 1: Typical Architecture

Digital Trunk Configuration

This chapter will introduce how to connect and configure a Digital trunk between a legacy PBX with a digital card (E1, T1 or J1) and UCM6510.

We consider that UCM6510 is already peered with the VoIP Provider via SIP Trunk, for more information on how to setup a VoIP trunk please refer to the SIP Trunk Guide.

Connecting Digital Port

To connect the UCM6510 with a legacy PBX having a digital card interface, users will need first to connect each others via a crossover cable depending on the digital trunk used, users could check with their Service Provider to get the correct cable.

The following figure shows the UCM6510’s front view to locate the T1/E1/J1 port.

Figure 2: UCM6510 Front View

Configuring Digital Trunk

After connecting digital ports of the UCM6510 and PBX, users will need to configure the port type and channels, in order to create a digital trunk.
E1 Digital Trunk will be used as example to configure ports, channels and creating the Digital Trunk, and make the UCM6510 as Master while the legacy PBX will act as Slave.

Configuring Digital Channels and Ports

To configure digital channels and ports on UCM6510 please follow below steps:

  1. Go to UCM6510 WebUI🡪PBX Settings🡪Interface Settings🡪Digital Hardware.
  2. Click on  under option to define the digital hardware type.
  3. Set Span Type to digital trunk’s type (“E1” in this example).
  4. Set Clock to “Master” and Signaling to “PRI_CPE” (assuming that the legacy PBX’s digital card will act as Slave). Or set Clock to “Slave” and Signaling to “PRI_NET” if legacy PBX is acting as Master.
Figure 3: Editing Digital Ports on UCM6510 Acting as Master
Figure 4: Editing Digital Ports on UCM6510 Acting as Slave
  1. Click on Save button to save changes.
  2. Access to PBX🡪Ports Config🡪Digital Hardware and click on  next to “DefaultGroup1” to set number of “Used Channels” on this trunk.
  3. Click on Update, then click on Apply Changes to save the settings.
Figure 5: Selecting Channels
Note

  • The default setting in default group has all the channels included. Users will need to modify default group to make sure the number of used channels is within the max number of channels allowed for T1, E1 or J1. For example, channel 16 is always used in E1 for signaling (channel 24 in T1/J1).
  • If all the channels are used in default group, users cannot create another group since all channels are already taken by default group.
  • Users can create a new group using other available channels, by clicking on

Creating a Digital Trunk

After Configuring Ports and Channels, users can create a Digital Trunk to peer both traditional PBX and UCM6510.

To create a Digital Trunk, follow the below steps:

  1. Go to UCM6510 WebUI🡪Extension/Trunk🡪Digital Trunks.
  2. Click on “Create New Digital Trunk”.
  3. Set the Trunk’s Name, and select the Channel Group to be used (“DefaultGroup1” in this example).
Figure 6: Create a Digital Trunk
  1. Click on Save button then Apply Changes.
  2. Users can check the Trunk’s status under System Status 🡪 Dashboard 🡪 Trunks.

Outbound/Inbound Routes

Once the Digital Trunk is up and available, now we can configure the calling rules to allow users behind the legacy PBX without VoIP capability to receive/make calls through the UCM6510 acting as Digital Gateway, considering that a SIP Trunk is already set between the VoIP provider and UCM6510.

In the figure below, we will use an example where phones behind the legacy PBX will dial numbers that begins 001 which will go through the UCM6510 acting as Digital Gateway, and receive calls that begins with 007.

Users can use this example and change patterns to match their actual numbering plan.

For more details about configuring Inbound/Outbound routes, please refer to “How to Manage Inbound / Outbound Routes on UCM6XXX” guide.

Figure 7: Inbound/Outbound Routes Example Scenario

Creating Outbound Route

For this scenario, we need to create 2 outbound routes on UCM6510:

  • Outbound Route 1: This route will allow outbound calls to numbers with leading 007 to go through Digital trunk (E1 trunk).
  • Outbound Route 2: This route will allow outbound calls to numbers with leading 001 to go through VoIP trunk (VoIP provider).

Follow below steps to create outbound routes:

  1. Go to UCM6510 WebUI🡪 Extension/Trunk🡪 Outbound Routes.
  2. Click on “Add”.
  3. Set the following:
    1. Calling Rule Name: Name to identify this rule (example: “E1_Gateway_OUT”).
    2. Pattern: Matching rule to route outbound calls via the trunk (example: “_007X.”).
    3. Privilege level: Set privilege to allow callers with same level or higher to use this route.
  4. Choose the Digital Trunk set earlier, in Main Trunk field.
  5. Click on Save button, then Apply Changes to save the configuration.
Figure 8: Outbound Rule through Digital Trunk

Now that the first outbound route is created (for outbound calls through digital trunk), repeat above steps to create a new outbound route through VoIP trunk using 001X. as pattern. Refer to figure below.

Figure 9: Outbound Rule through VoIP Provider

Creating Inbound Route

For this scenario, we need to create 2 inbound routes on UCM6510 and should have option “Dial Trunk” enabled:

  • Inbound Route 1: This route will allow incoming calls to numbers with leading 001 through Digital trunk (E1 trunk) to reach UCM6510 and be processed.
  • Inbound Route 2: This route will allow incoming calls to numbers with leading 007 through VoIP trunk (VoIP provider) to reach UCM6510 and be processed.

Follow below steps to create inbound routes:

  1. Go to UCM6510 WebUI🡪 Extension / Trunk 🡪 Inbound Routes.
  2. Select the Digital Trunk from Trunks.
  3. Click on “Add”.
  4. Set the DID pattern (“_001X.” used in our calling scenario example).
  5. Set Destination as “ByDID”.
  6. Make sure to check Dial Trunk to allow users to use the VoIP trunk with provider.
  7. Click on Save, then Apply Changes.
Figure 10: Inbound Rule through Digital Trunk

Now that the first inbound route is created (incoming calls through digital trunk), repeat above steps to create a new inbound route through VoIP trunk using “007X.” as pattern. Refer to figure below.
