Extending converged, intelligent Business Communications
Applications to the small branch office.

Avaya G250 DCP Overview

The Avaya G250 Media Gateway is a powerful branch communication solution that packs an IP telephony gateway, an advanced IP WAN router, and a high-performance LAN switch into a compact, 2U high 19” rack mount unit. The G250 Gateway is a new member of the Avaya branch gateway product line that extends the Avaya Business Communications Applications from a headquarters location to a branch. It is ideally suited for enterprises with multiple branch locations needing from 2 to 12 extensions.

The system gains its functionality from a centralized Avaya Media Server running Avaya Communication Manager, and includes several survivability options for increased reliability and confidence. Alternatively, where a stand-alone branch solution is desired, the G250 Gateway can operate as a stand alone system with Avaya Communication Manager running on an internally installed media server. As part of the Avaya Media Gateway family, the G250 can be installed in very small branch locations, while the Avaya G350 and G700 Media Gateways serve small and medium sized branches, delivering commonality across the entire enterprise.

A Complete Branch Office Solution

The G250 Gateway is designed to meet the increased communication needs of branch offices by connecting everyone in an organization regardless of where they work. All users in an enterprise can now have access to a full set of enterprise communication applications. No longer do branch employees have to settle for a separate, often isolated communication system that requires them to remember different dialing codes to reach other employees. Additionally, with a single set of centralized applications, management is significantly simpler than managing multiple systems serving each branch location.

High Availability

With several powerful survivability options, the G250 Media Gateway can be installed with confidence that communications will continue to work even if the connection back into the main system is lost. The G250 survivability features include:

• Standard Local Survivability: Embedded capability provides operations if connection into the centralized
• Modem Dial Back-up: Allows the gateway to reconnect to the centralized Avaya Media Server over a modem if the main connection is lost.
• Enhanced Local Survivability: An Avaya S8300 Media Server can be installed in the G250 Gateway to operate as a Local Survivable Processor delivering 100% of the Avaya Communication Manager features.
• Connection Preserving Migration: Keeps calls connected if the gateway loses connection and is migrating to a backup connection or an alternative media server.

 

Single box solution

The Avaya G250 also functions as an edge router to
support the consolidation of voice and data traffic over
an IP network. Optional IP WAN routing media modules
add support for PPP/Frame Relay connectivity over E1/
T1 or Universal Serial Port (USP) interfaces. The G250
media gateway can also connect to an external WAN
device via a fixed 10/100 Ethernet WAN router port,
which supports traffic shaping to match data transfer
rates with available WAN bandwidth.

End-to-end security

The G250 Gatewaycomplies with the Avaya end-toend
security architecture, delivering advanced security
features such as AES encryption and integrated VPN.
The G250 Gateways are also available in FIPS 140-2
certified versions meeting the U.S. Government’s most
demanding security requirements. Because the gateway
is typically installed as part of an enterprise-wide Avaya
Communication Manager solution, system and security
management is enhanced providing a lower total cost
branch solution.

Avaya Universal Paging Access Module

Avaya Universal Paging Access Module
Features Overview

The following provides an overview of the features of the Avaya Universal Paging Access Module.

24V or 48V Operation(Trunk Port Operation) — MODE switches let you select 24V (not included) or 48V (included)
power supply. A 48-volt power supply is included to provide 48-volt trunk
port operation.

Pre-announce and Confirmation tones — A pre-announce tone (heard at the telephone and the loudspeakers) or (heard only at the telephone) can be selected with Tones MODE switches. (One of these modes must be selected for the unit to operate properly.) A screwdriver-adjustable control (TONE VOL) sets the level of each. (NOTE: When used with ground-start trunk ports, only the pre-announce option can be used.)

VOX Delay Timer — Voice-controlled disconnect timer, for use in station port operation is enabled with a MODE switch. This automatically disconnects the line after a predetermined interval of silence (from 2 to 6 seconds, set with the VOX DELAY control; the setting may be critical with telephone systems that issue a rapid recorder tone after the paging party hangs up).

Default Timer — A default timer sets the maximum time allotment for paging (6 to 35
seconds, set with the PAGING TIME control). This timer ensures that the unit will always disengage the line by forcing a disconnect, if the other disconnect functions are disabled or not available with a specific telephone switch. Note: The timer may be extended or inhibited.

Background Music Input Jack and Volume Control —An RCA-type jack (BGM IN) accepts background music sources from the paging system. The level can be set with the BGM VOL control.

Contact Closures—Two normally-open contact closures are provided on the UPAM which change state when the unit is activated. One set is located on the punch block (terminals N.O. and COM) and the other set is located on the bottom side of the unit (terminal strip).

Avaya 655A Power Supply

 

Solution Overview

The Avaya G650 can use one or two Avaya 655A power supplies that can have both AC and DC input power
present. Either power supply can provide all the power needed by the G650. When there are two power supplies, they share the power load. One power supply can operate on AC power and the other on DC power. But, if AC power is available, the system always uses AC power.

The Avaya 655A power supply is:

• The only power supply supported in the G650
• Not backward compatible to other carrier types

If you use only one Avaya 655A power supply, place it in slot 0. If you are using two power supplies, place them in slots 0 and 15.

Note: You can insert or remove a redundant power supply and not affect the G650 if the other Avaya 655A power supply is operating.

---

 

Avaya 655A Power Supply Detailed Description

 

Input Power

The Avaya 655A power supply can operate on either AC or DC input power. But, if AC power is available, the system always uses AC power. One power supply can operate on AC power, and the other on DC power. The power supplies use AC power first and switch to DC power if AC power fails or is not present.

 

AC Power

Commercial AC is the primary input power source. Both slot 0 and slot 15 have dedicated AC input. The Avaya 655A power supply can operate on AC input that ranges from 90 to 264 VAC at 47 to 63 Hz. The nominal ranges for AC power are:

• 100 to 120 VAC at 50 or 60 Hz
• 200 to 240 VAC at 50 or 60 Hz

 

DC power

Minus 48VDC power can be supplied simultaneously as backup power. One -48VDC power input point is provided on the G650 backplane and is distributed through the backplane to each power supply.

LEDs

The five LEDs on the faceplate of the Avaya 655A power supply are in a vertical line with the red LED on top. These five LEDs provide the following status:

• Red – This LED:
  – Lights when there is a failure in either the power supply or the fans. For a Avaya G650 with
  redundant power supplies, a failure in the fan assembly results lights this LED on both
  power supplies.
  – Flashes off once per second when the software shuts down the ring voltage output of a
  power supply
• Yellow – This LED:
  – Lights when the status of the power supply and fans is OK
  – Flashes once per second when the software shuts down a single power supply, in a
  carrier with operational redundant power supplies
• Green – Lights when there is AC power applied to the power supply
• Green – Lights when there is DC power applied to the power supply
• Green – Lights when the power supply is supplying ringing to the G650

 

Avaya 655A ring generation

The Avaya 655A provides either North American ringing (20Hz) or European/International (25Hz) ringing. The 655A also has a setting to provide no ringing. This setting is applicable when the customer supplies a ring generator that is external to the power supply. An example of an external ring generator is the TN2202 French ringing circuit pack. The 655A power supply provides a physical slide switch to select the frequency of the ring generator. The options are:

• 20Hz — North American
• 25Hz — European and international
• Other — No ringing output. Applicable when an external ring generator is used such as the
  TN2202 French ringing circuit pack.

You must remove the power supply from the G650 when you change the ringing frequency selection. The ringing frequency selection switch is on the back of the power supply. Only one 655A supplies ringing to the Avaya G650. The power supply in slot 0 in the Avaya G650 with an A carrier address is the default for ringing. The system uses this default Avaya 655A unless the Avaya 655A has failed or the software has commanded it to shut down. When a G650 carrier has redundant power supplies, one supply automatically supplies ringing if the other power supply fails. A Avaya 655A provides ringing to only one G650 carrier. For example, the 655A power supplies in carrier A supply ringing to carrier A only. Meanwhile, the power supplies in carrier D supply ringing to carrier D only. If the ring generation in both of a carrier’s power supplies fail, no other power supply provides ringing for the carrier.

This Item sells in Refurbished Condition and as always it will be delivered in A++ condition.
