Overview of Cisco VG450 Voice Gateway

Cisco High-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 fixed-port (FXS and FXO) modules 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

VG450 Voice Gateway is a high-density analog voice gateway. It is an intermediate path that enables TDM to IP transition.

The Cisco VG450 Voice Gateway supports the following interfaces:

• Gigabit Ethernet (GE)

• USB

• Network Interface Module (NIM)

• Single-Wide Service Module (SWSM) interface

• Double-Wide Service Module (DWSM) interface

Features and Benefits of Cisco VG450 Voice Gateway

Cisco VG450 Voice Gateway provides VoIP connectivity to analog devices, such as analog desk phones, analog conference room phones, fax machines and modems. Cisco 450 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 service modules 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.

• Support for Online Insertion and Removal (OIR)— The FXS and FXO service modules support Online

Insertion and Removal (OIR), reducing the downtime required for new or replacement modules. The

Features and Benefits of Cisco VG450 Voice Gateway service modules can be inserted into the SM-X slot on the supported Cisco 4000 Series ISRs without powering off the router.

• 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)

• Higher ringing voltage (65 Vrms, no load)

Note Switching between the modes requires reload of the ISR chassis.

• FXO failover bypass ports— A failover bypass port, also called a failover trunk bypass, provides a way to use designated analog phone ports to make phone calls through the PSTN during a power outage.

In addition to these features, Cisco 450 Voice Gateway supports the following features:

• Caller line ID

• G.711, G.729a, and G.726

• G722, iLBC, GSMAMR-NB, and Internet Speech Audio Codec (iSAC)

• Fax detection, pass-through, and relay (T.38)

• Modem pass-through

• DTMF detection

• Echo cancellation

• Voice activity detection

• Comfort noise generation

• Real-Time Control Protocol (RTCP)

Analog Phone Connectivity

Analog Phone Connectivity

Cisco 450 Voice Gateway are ideal for analog phone deployments ranging from centralized to sparsely concentrated or distributed topologies. Cisco 4000 Series Integrated Services Routers offer many supplementary analog calling features, depending on the call control and signaling type used. All supplementary analog features are supported through the FXS and FXO service modules. The analog interface on Cisco 4000 Series also supports Feature Access Codes (FACs) for invoking supplementary services.

Fax and Modem Connectivity

FXS ports on Cisco 450 Voice Gateway support fax machines and modems. When using fax machines, the gateways support T.38 fax relay and fax pass-through. T.38 fax relay technologies allow transfer of faxes across the network with high reliability using less bandwidth than a voice call. All modems can be connected to the Cisco VG Series Gateways and are transferred over the network using modem pass-through.

Protocols Supported

The voice gateways support the following protocols:

• SCCP

• H.323v4

• MGCP

• SIP

• Real-Time Transport Protocol (RTP)

• Secure Real-Time Transport Protocol (SRTP)

• Trivial File Transfer Protocol (TFTP)

• HTTP server

• Simple Network Management Protocol (SNMP)

• Telnet

• Dynamic Host Configuration Protocol (DHCP)

• DNS

• Cisco Unified Communications Manager or Cisco Unified Communications Manager Express redundancy support using Hot Standby Router Protocol (HSRP)

• Call survivability: MGCP failover to an H.323 connection to the Survivable Remote Site Telephony

(SRST) router

• T.38 fax relay and modem pass-through

• Codec support: G.711, G.729. G.729a will be used if the gateway does not support G729 annex b

Location and Mounting Requirements

The mounting possibilities for your Cisco VG450 Voice Gateway are:

• Rack-mount

• Bench-top

The mounting location must provide the following:

Temperature Control and Ventilation

The installation location (room, closet, or cabinet) for the Cisco VG450 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 122°F (0 to 50°C).

Note The Cisco VG450 Voice Gateway chassis is designed for back and sides-to-front airflow.

Enclosed Racks

Caution Enclosed racks must have adequate ventilation. An enclosed rack should never be overcrowded and should have louvers and a fan.


9


Bench-Mounted

If the Cisco VG450 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 VG450 Voice Gateway are not blocked.

Tip 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.

Bench-Mounted

If the unit is placed on a bench-top, do not stack other equipment or paper on the chassis. Provide plenty of space for air circulation (front to back). Inadequate ventilation can result in overheating and damage.

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.

Note Enclosed racks must have adequate ventilation. An enclosed rack should never be overcrowded and should have louvers and a fan

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 VG450 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.

10



Power Source

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

A Cisco VG450 Voice Gateway with AC power supply autoselects either 100–127 volt or 200–240 volt operation. AC versions include a 6-foot (1.8-meter) electrical power cord. (A label near the power cord indicates the correct voltage, frequency, current draw, and power dissipation.)

Power Suppy Considerations

Cisco VG450 Voice Gateway requires significantly more power because of its high-density ports and OPX

‘Lite’ requirements.

This require a larger 48V battery backup that may need to be custom built.

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). Thus, a separate

UPS for Cisco VG450 Voice Gateway is a viable option when the ISR/UPS is not co-located with it.

If you suspect that your AC power is not clean—if lights flicker often or there is machinery with large motors nearby—have a qualified person test the power. Install a power conditioner if necessary.

Warning Avoid using or servicing any equipment that has outdoor connections during an electrical storm. There may be a risk of electric shock from lightning. Statement 1088

Warning Read the installation instructions before you connect the system to its power source. Statement 1004

Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than:120 VAC, 15A U.S. (240 VAC, 10A international) Statement 1005

Warning The device is designed for connection to TN and IT power systems. Statement 1007

Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means by security. Statement 1017

Network Cabling Considerations

The cable types that are used are dependent on the Cisco VG450 Voice Gateway that you are using. For more information, see the “Cable Specifications and Information” section on page A-1 .


11


Distance Limitations for Interface Cables

The following are the cable types that are used in the Cisco VG450 Voice Gateway:

• GE cables (RJ-45 to RJ-45 straight-through cables)

• Analog voice cables (RJ-21)

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.

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 VG450 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 centers cannot resolve such infrequent, but potentially catastrophic problems 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).

Safety Tips

• Keep tools away from walk areas where you and others could fall over them.

• Do not wear loose clothing that could get caught in the chassis.

• Wear safety glasses if you are working under any conditions that might be hazardous to your eyes.

Safety Tips

Use these tips as safety guidelines when installing or working around this equipment:

• Locate the emergency Power-off switch for the room in which you are working. Then, if an electrical accident occurs, you can act quickly to turn off the power.

• Disconnect all power before installing or removing a chassis.

• Do not work alone if potentially hazardous conditions exist.

• Never assume that power is disconnected from a circuit. Always check.

• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.

• If an electrical accident occurs, proceed as follows:

• Use caution; do not become a victim yourself.

• Turn off power to the system.

• If possible, send another person to get medical aid. Otherwise, assess the condition of the victim and then call for help.

• Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD occurs when electronic components are improperly handled; it can result in complete or intermittent failures.

Always follow ESD-prevention procedures when removing and replacing components.

• Ensure that the chassis is electrically connected to earth ground.

• Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact.

• Connect the clip to the ESD-strap connection jack (to the left of the power switch on the rear of the chassis) or to an unpainted chassis frame surface.

Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohm (Mohm).

Unpacking and Inspection

Do not unpack the Cisco VG450 until you are ready to install it. If the installation site is not ready, keep the chassis in its shipping container to prevent accidental damage.

The Cisco VG450, cables, printed publications, and any optional equipment you ordered might be shipped in more than one container. When you unpack each shipping container, check the packing list to ensure that you received all the following items:
