Chapter 1: Overview

Echo-Cancellation

Administrators connecting their Gateway Series appliances to the PSTN or other devices are likely to be placing calls that will result, at some point, in an unbalanced 4-wire/2-wirehybrid. The result of this hybrid is the reflection of anear-endecho to the calling party. Elimination of this echo is the responsibility of echo cancellation.

The Gateway Series appliance utilizes hardware-basedvoice processors for echo cancellation and codec transcoding. Its hardware echo canceller is designed to handle up to 128ms of echo cancellation across all channels and provides a G.168 compliant echo cancellation solution.

If not explicitly disabled in the Gateway Series web GUI, the hardwarebased echo canceller will automatically operate and cancel all network echo within its tail range (1024 taps).

Hardware Installation

This section describes how to properly install the hardware for a Gateway Series appliance.

Caution

Only qualified service personnel should continue with hardware installation and configuration of the Gateway Series appliance. Users should not attempt to perform these functions themselves.

Caution

This equipment is intended for use in Restricted Access Areas only where equipotential bonding has been applied.

Grounding

The Gateway Series appliance must be properly earth grounded for safety reasons. If the unit is not properly earth grounded, the unit and/or other equipment connected to the unit could be damaged. If a Gateway Series appliance is damaged while it is improperly grounded, the warranty on the Gateway Series appliance is void.

A ground lug is located on the opposite side from the front panel of a Gateway Series appliance. Attach an appropriate length and gauge of wire to the double-crimpground ring terminal. The wire length should be as short as possible, and gauge should be 18 AWG or greater. Stranded or solid wire is acceptable. Wire is not provided with the Gateway Series

Digium, Inc.

Chapter 2: Unit Installation

appliance. Double crimp the ground ring terminal to the wire. Next, slide the ground ring terminal over the ground lug. Then fasten the ground ring terminal to the ground lug using the ground nut. The ground nut must be turned clockwise to tighten it onto the ground lug. The opposite end of the wire that is connected to the ground ring terminal should be securily fastened to an unpainted metalic section of a properly earth grounded equipment rack. A connector for the opposite end of the wire is not provided with the Gateway Series appliance.

Note: Taking into consideration the requirements of all equipment connected to or sharing the rack, the equipment rack should be properly earth grounded. Refer to the manufacturer of the rack for instructions on how to properly earth ground the rack.

Important

Use only a grounded electrical outlet when connecting the Gateway Series appliance to a power source. If you do not know whether the outlet is grounded, consult with a qualified electrician.

Digium, Inc.

Page 25

Chapter 2: Unit Installation

Mounting

The included hardware allows the Gateway Series appliance to be wall mounted, rack mounted side-by-sidewith another Gateway Series appliance, or placed flat on a level surface. If a single Gateway Series appliance is to be rack mounted, the optional long mounting bracket (not supplied, part number3244-00042)must be used. The optional long mounting bracket can be ordered by contacting a Digium reseller or Digium directly.

Important

Reliable earth grounding of rack-mountequipment should be maintained. Particular attention should be given to provide connection other than direct connections to the branch circuit (e.g., use of power strips).

Important

Mounting of the Gateway Series appliance in a rack should be such that no hazardous condition is achieved due to uneven mechanical loading. Do not place heavy objects on top of the unit, or pull down on the mounted unit. Consider the mechanical loading of external cables. The weight of the cables can pull on the unit and create uneven loading. Secure heavy cables with external cable trays.

Important

If rack mounting, install the Gateway Series appliance in a rack so that the amount of airflow required for safe operation is not compromised.

Digium, Inc.

Page 26

Chapter 2: Unit Installation

Important

If the Gateway Series appliance is installed in a system that is in turn installed in a closed or multi-unitrack assembly, the operating ambient temperature of the rack environment may be significantly greater than the room ambient. While the maximum safe operating temperature is 50°C, consideration should be given to installing the unit in an environment compatible with the maximum recommended ambient temperature of 45°C for long term reliability and maximum performance.

Single Unit Rack Mount:

In order to rack mount the Gateway Series appliance by itself, place one of the short mounting brackets on the front of one side of the Gateway Series appliance. Line up the holes from the mounting bracket to the threaded holes on the front side of the Gateway Series appliance. Two #8 black truss head screws should be inserted and turned clockwise to fasten the mounting bracket. Do not over-tighten.Repeat these steps when installing the optional long mounting bracket (not supplied, part number3244-00042)on the other side of the Gateway Series appliance.

Chapter 4: Troubleshooting

Firmware Recovery and Configuration Reset

If a Gateway Series appliance is behaving unexpectedly or the password is forgotten, a firmware recovery may need to be performed. The USB Recovery port can be used to perform a firmware recovery using a recovery image. The recovery image reformats the Gateway Series’ root filesystem and reloads the appropriate software on it. It will also overwrite the configuration database, returning the Gateway Series appliance to its default configuration.

Note: It is highly recommended to use an image that is equal or greater in version than the firmware that is currently installed on the Gateway Series appliance.

Every Gateway Series firmware release will include a recovery image. The recovery image is located inside of a compressed zip file which can be downloaded from http://downloads.digium.com/pub/telephony/gateway/recovery/. After downloading the recovery image, the contents of the compressed zip file must be extracted and copied to the root (i.e. parent) directory of anempty USB flash drive.

Note: A USB flash drive is not provided with a Gateway Series appliance. It must be purchased separately. The USB flash drive should be at least 2GB in size and formatted with the FAT32 filesystem.

Note: Some decompression utilities will create a new directory in which to place extracted files. If your decompression utility functions in that way, be certain to copy the contents from that new directory to the root (i.e. parent) directory of anempty USB flash drive. Any new directory created by a decompression utility should not be copied.

Digium, Inc.

Chapter 4: Troubleshooting

Next, power off the Gateway Series appliance.

Note: For hardware revisions A3 and earlier, the Gateway Series appliance must remain powered off for 60 seconds in order to guarantee proper startup. See the label on the back of the Gateway Series appliance to determine the hardware revision.

Then insert the USB flash drive into the USB Recovery port. Power on the Gateway Series appliance. The Gateway Series appliance will boot from the USB Recovery port and process the recovery image which was placed on the USB flash drive.

Warning! Do not disconnect power during this process. The recovery process will take at least 3 minutes to complete.

During this process, the Device Status LED will turn red for a fraction of a second. Then it will turn amber for less than a minute. Next, it will run red for about 2 minutes. Lastly, the Device Status LED will remain off. At this point, it is safe to power off the Gateway Series appliance. Remove the USB flash drive and power cycle the Gateway Series appliance.

Chapter 4: Troubleshooting

What type of cable do I need for the T1/E1 ports on a Gateway Series appliance?

A straight-throughRJ45 T1/E1 cable is needed for connecting to the RJ45 ports on a Gateway Series appliance when connecting to the PSTN. If connecting to a TDM PBX, a crossover RJ45 T1/E1 cable may be required. Use only shielded cables to ensure compliance with the International EMC standards. The appropriate cables may be ordered from Digium by visitingwww.digium.com. Refer toTable A-2 on page 86 for pin assignments.

How can the Gateway Series software be reinitialized without modifying any configuration settings?

The Gateway Series software can be reinitialized without modifying any configuration settings by following the steps described below.

1.Press the reset switch once.

2.The status LED will flash amber for 5 seconds.

3.The status LED will flash red for 2 seconds, acknowledging the reinitialization request.

4.The Gateway Series appliance will restart itself.

5.The status LED will turn green once the reinitialization is complete.

How can the Gateway Series GUI password be reset to its default without modifying any configuration settings?

Digium, Inc.

Page 81

Chapter 4: Troubleshooting

The Gateway Series GUI password can be reset to its default without modifying any configuration settings by following the steps described below.

1.Press the reset switch once.

2.The status LED will start flashing amber.

3.Press the reset switch again while the status LED flashes amber.

4.The status LED will flash green for 2 seconds, acknowledging the reset password request.

5.The password is set back to its default (i.e. “admin”).

There is a slight echo. How can I adjust the sound quality?

First, verify that the Echo Cancellation option under thePort # menu ofT1/E1 Settings is enabled. If it is not, enable it. If echo persists, adjust theRX Gain andTX Gain options on the same menu. For the gain options, it is recommended to shift only between values of-5and 5.

How is the loopback test useful for troubleshooting?

The loopback test verifies the integrity of the data being transmitted and received on the T1/E1 port by sending a pattern out of the T1/E1 transfer pins and expecting to see the same pattern come back on the receive pins. This test requires that the T1/E1 port be disconnected from any external device and a loopback connector be inserted to the port. A loopback connector has pin 1 looped to pin 4, and pin 2 looped to pin 5.
