Dialogic® 2000 Media Gateway Series Installation and Configuration Note

1. Scope

This document is intended to detail a typical installation and configuration of Dialogic
Gateway Series (DMG2000) when used to interface between a PBX or Central Office and
Microsoft

®

Lync 2010.

3. Prerequisites

3.1 Trunk Prerequisites

The T1 or E1 trunk must be configured for T1 (NI2, QSIG, 5ESS or DMS protocols) or E1 (Euro
ISDN or QSIG protocols).

If connecting to a PBX, refer to the Unified Messaging Integration Notes for guidance at:

http://www.dialogic.com/support/helpweb/mg/iw1904.aspx

For more information on PBX programming, refer to:

http://www.dialogic.com/solutions/unified-communications/microsoft-pbx-interop-and-config­guides.aspx

3.1.1 Cabling Requirements

Cabling for ISDN connections must be CAT5e or better. Standard voice quality cable will not
provide optimum signal quality, and will cause the gateway to experience problems establishing a
connection on the D-Channel.

If connecting the gateway directly to the PBX, it may be necessary to use a T1 crossover cable
(Pin 1 is connected to Pin 4 and Pin 2 is connected to Pin 5). This is dependent on the PBX type to
which the gateway is being connected, so if af ter connecting the gateway to the PBX the Alarm
light on the front of the gateway remains “Red”, try using the crossover cable.

3.2 Gateway Prerequisites

The DMG2000 must be installed with Version 6.0.SU6.0.004_B003.

4. Summary of Limitations

No limitations noted as of the last update to this document.

5. Gateway Setup Notes

5.1 Initial Setup

There are two options for performing the initial configuration of the DMG2000 – serial or IP. It is
recommended that serial be used.

During the initial setup of the DMG2000, you will be setting the following parameters:

• Assign the gateway a unique IP address, subnet mask and IP network gateway address (if
the latter is required).

• Configure the gateway to use the SIP VoIP protocol.

• Set the Line Mode to T1 or E1.

• Set the Protocol to match your trunk setting.

Connecting to Console Port

Serial:

Connect to the COM 2 port on the DMG2000 using an appropriate program, such as
HyperTerminal.

The serial port configuration is:
Baud rate: 115200

Data Buts 8

Change the IP address of your computer to be in the same subnet as the default. Telnet into the
DMG2000 and then follow the commands noted below:

Running QuickCFG

Press Enter key until you get to the “PIMG” prompt. Follow the steps below and modify the

5.2 Final Web Configuration

Once the initial configuration is complete and the DMG2000 has been reset, it is necessary to log
into the web interface by browsing to the IP address of the DMG2000 using “admin” as the user
and using the gateway password (“IpodAdmin” is the default).

Sample Configuration files

Download available at:

http://www.dialogic.com/~/media/microsoftuc/DMG2000_Lync_Config.zip

• There are two sample configuration files for adjusting gateway paramet ers to enable
interoperability with Microsoft

®

Lync 2010 specific settings. The “DMG2000 Lync Config
u-law.ini” file, among other functions, will set up the codec to be G.711 uLaw for use in
North America and other areas that use uLaw. The “DMG2000 Lync Confi g a-law.ini”
file, among other functions, will set up the codec to be G.711 aLaw for use in Europe and
other regions that use aLaw. In addition to changing the default settings, these files also
contain some sample Dial Plan configurations to provide a starting point for configuration
the E.164 phone number conversions.

• To import one of these files into the DMG2000, use the Import/Export page on the
DMG2000 web interface. Select IMPORT and browse to reach the desired “.ini” file to
import.

Setting T1 / E1 Parameters

Line Encoding and Framing

It is necessary to ensure that the Line Encoding and Framing match those of the T1
or E1 line coming from the PBX or Central Office.

ISDN Protocol

Since ISDN protocols are not necessarily symmetric protocol it is necessary to
determine which device (PBX or Gateway) is going to function as the Network side
of the protocol. It is recommended that if the PBX can support Network side that it
be configured as Network in which case the gateway needs to be configured as
Terminal. Setting the Protocol side is done by changing the “Telephony Port
Interface Side” to the setting you want the gateway to function.
