Introduction to Cisco VG400 Voice Gateway
Cisco medium-density Analog Voice Gateway provide enterprises, managed services providers, and service
providers the ability to directly connect public-switched telephone networks (PSTNs) and existing telephony
equipment to Cisco 4000 Series Integrated Services Routers. These FXS and FXO ports provide Dual-Tone
Multifrequency (DTMF) detection, voice compression and decompression, call progress tone generation,
Voice Activity Detection (VAD), echo cancellation, and adaptive jitter buffering. Cisco VG400 Voice Gateway
is a medium-density analog voice gateway. It is an intermediate path that enables TDM to IP transition.
The Cisco VG400 Voice Gateway supports the following interfaces:
• Two RJ45 Gigabit Ethernet (GE) ports
• One RJ45 Console Port
• One USB 2.0 Port
• LED for System, GE Port, and Console Port Status

Features and Benefits of Cisco VG400 Voice Gateway
Cisco VG400 Voice Gateway provides VoIP connectivity to analog devices, such as analog desk phones,
analog conference room phones, fax machines, and modems. Cisco 400 Voice Gateway provides several
improvements from the previous high-density analog and digital extension modules (EVMs), in the following
ways:
• On-board Digital Signal Processor (DSP)—The FXO and FXS ports contain an onboard DSP and
don’t require the router to have a dedicated packet voice DSP module (PVDM) on the motherboard. The
DSP on the voice module is necessary for the voice features. It also provides for echo cancellation of up
to 128-ms echo-tail length for demanding network conditions.
• FXS-E (extended loops) support—FXS ports on the new modules support FXS-E with the following
details:
• Higher loop current (35 mA) to accommodate specialty phones
• Longer loop length for loops with 26 AWG wire, up to 11,000 feet (3400 meters)

Slot, Bay, and Ports
Slot, Bay, and Ports
The FXO port is used to connect to PBX or key systems, or to provide off-premises connections to the PSTN.
It supports battery reversal detection and caller ID. The FXO port is also used to connect to analog Centralized
Automatic Message Accounting (CAMA) trunks to provide dedicated E-911 service (only in North America).
The FXS port is used to connect analog phones, modems, fax machines, and speaker phones to an enterprise
IP voice system, to use them as extensions to your Cisco or third-party IP call-control system. Having these
devices tightly integrated with the IP-based phone system is advantageous for increased manageability,
scalability, and cost-effectiveness. The Direct Inward Dialing (DID) port is used to provide off-premises DID
connection from the central office. It serves only incoming calls from the PSTN. The Caller ID feature is not
supported in DID mode.

Planning Your Installation
This chapter provides preinstallation information, such as recommendations and requirements that must be
met before installing Cisco VG400 Voice Gateway. Before you begin, inspect all items for shipping damage.
If anything appears to be damaged or if you encounter problems installing or configuring the Voice Gateway,
contact the customer service. Warranty, service, and support information is included in the Hardware Quick
Start guide that is shipped with your product. See the following sections to prepare for installation:
• Location and Mounting Requirements, on page 11
• Temperature Control and Ventilation, on page 12
• Rack requirements, on page 12
• Access to Chassis, on page 12
• Power Source and Supply, on page 12
• Network Cabling Considerations, on page 13
• Interference Considerations , on page 14
• Required tools and equipment for installation, on page 14
• Site Log, on page 15
• Installation Checklist, on page 15
Location and Mounting Requirements
The three mounting possibilities for your Cisco VG400 Voice Gateway are as follows:
• Rack-mount
• Wall-mount
• Bench-mount
The mounting location must provide the following:
• Access to the chassis.
• Access to a suitable power source.
• Access to an appropriate earth ground.
• Allowance for adequate heat dissipation and airflow around the chassis.
Cisco VG400 Voice Gateway Hardware Installation Guide
11
Planning Your Installation
Temperature Control and Ventilation
Temperature Control and Ventilation
The installation location (room, closet, or cabinet) for the Cisco VG400 Voice Gateway should always be
well ventilated and provide adequate air circulation to ensure proper cooling. The room temperature should
be maintained between 32 to 104°F (0 to 40°C).
Note
The Cisco VG400 Voice Gateway chassis is designed for back and sides-to-front airflow.
Rack requirements
The following information can help you plan your equipment rack configuration:
• Allow clearance around the rack for maintenance.
• Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because the hardware
generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Heat
generated by equipment at the bottom of the rack can be drawn upward into the intake ports of the
equipment above it.
• When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or exhaust
ports. If the chassis is installed on slides, check the position of the chassis when it is seated in the rack.
If the Cisco VG400 Voice Gateway is installed in an enclosed rack with a ventilation fan at the top, make
sure that heated air drawn upward from other equipment does not prevent adequate cooling.
If the chassis is installed using slide rails, check for blocked ventilation ports when it is in position in the rack
or cabinet. Make sure that the ventilation ports of the Cisco VG400 Voice Gateway are not blocked.
Baffles can help isolate exhaust air from intake air. Baffles also help draw cooling air through the cabinet.
The best location for the baffles depends on the airflow patterns in the rack. You can test the airflow by
experimenting with different equipment arrangements.
Access to Chassis
Allow space at the rear of the chassis for cable connections. Also consider the need to access the chassis for
future upgrades, maintenance, and troubleshooting.
Chassis grounding is provided through the power cable, which uses a standard grounding plug. However, the
chassis also requires a reliable earth ground using the earth ground lug and hardware provided. For more
information, see the Chassis Grounding section.
Power Source and Supply
Check the power at your site to ensure that you are receiving “clean” power (free of spikes and noise). Install
a power conditioner if necessary.
Cisco VG400 Voice Gateway Hardware Installation Guide

Planning Your Installation
Network Cabling Considerations
A Cisco VG400 Voice Gateway with AC power supply auto selects power ranging from 100-240V. AC
versions include a 6-foot (1.8-meter) electrical power cord.
To handle power failure conditions, an uninterrupted power supply (UPS) is needed. UPS is widely available
in all markets, including emerging markets (due to prevalence of UPS for personal computers).
Warning
This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work
on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard
practices for preventing accidents. Use the statement number provided at the end of each warning to locate
its translation in the translated safety warnings that accompanied this device. Statement 1071
SAVE THESE INSTRUCTIONS
Warning
This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the
protective device is rated not greater than 20A Statement 1005
Network Cabling Considerations
The cable types that are used are dependent on the Cisco VG400 Voice Gateway that you are using. For more
information, see the Cable Specifications and Information in this guide..
The following are the cable types that are used in Cisco VG400 Voice Gateway:
• GE cables
• Analog voice cables (RJ-11)
Distance Limitations for Interface Cables
When planning your installation, consider distance limitations and potential electromagnetic interference
(EMI) as defined by the Electronic Industries Association (EIA). Distance limitation information is included
for the following VG ports:
• Gigabit Ethernet Maximum Distance: The maximum segment distance for Gigabit Ethernet is 330 feet
(100 meters) (specified in IEEE 802.3).
• FXS Analog Voice Port Maximum Distance: The maximum distance is established by a total allowable
loop resistance, including the phone or terminal equipment, of 600 ohms.
• FXS-E (Extended loop) Analog Voice Port Maximum Distance: The maximum distance is established
by a total allowable loop resistance, including the phone or terminal equipment, of 1400 ohms.
Note
Typically, a 26 AWG wire is equal to 81.6 ohm/Kft and 24 AWG wire is equal to 51.3 ohm/Kft.
Cisco VG400 Voice Gateway Hardware Installation Guide

Planning Your Installation
Interference Considerations
Interference Considerations
When you run cables for any significant distance in an electromagnetic field, interference can occur between
the electromagnetic field and the signals on the cables. This has two implications for the installation of terminal
plant cabling:
• Unshielded plant cabling can emit radio interference.
• Strong electromagnetic interference (EMI), especially as caused by lightning or radio transmitters, can
destroy the EIA/TIA-232 drivers and receivers in the Cisco vg400 Voice Gateway.
If you use twisted-pair cables with a good distribution of grounding conductors in your plant cabling, emitted
radio interference is unlikely.
If you have cables exceeding recommended distances, or if you have cables that pass between buildings, give
special consideration to the effect of lightning strikes or ground loops. If your site has these characteristics,
consult experts in lightning suppression and shielding. The electromagnetic pulse caused by lightning or other
high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic
devices.
Most data centres cannot resolve such infrequent, but potentially catastrophic problems just described without
pulse meters and other special equipment. Take precautions to avoid these problems by providing a properly
grounded and shielded environment and by installing electrical surge suppression.
If you remove any module, you must either install a module in its place or install a cover plate over the opening.
All module openings must be either occupied or covered to prevent electromagnetic interference.
For advice on the prevention of electromagnetic interference, consult experts in radio-frequency interference
(RFI).
