HIGH DENSITY GATEWAYS
The server’s high density gateways, also called a PIR (Port Interface Rack) is uniquely design. It is based on the proven build and expandability of local modular units called Port Interface Modules (PIM). Flexibility in system configuration and easy cost effective growth are advantages of this design. A PIR provides multiple universal card slots for access to a maximum of 384 ports. The PIR’s are compact, 19” rack mounted units that connect to the server for control and also out to external cabling frames via plug-in cables to allow for terminals or trunk connection. To maximize the utilization of space and simplify system set up, most general interface packages can be placed in any PIR slot.
8RU HIGH DENSITY GATEWAY
The 8RU PIR is powered by a48v DC or 100v-240v AC source. This PIR offers 17 universal card slots allowing for an extensive range of line and trunk card options as well as providing dedicated special services card slots for packages such as registers.
Redundancy options,DC-DC power supply packages, and TSW/MUX packages are also accommodated by the 8RU PIR.
Connectivity between the TDM side and the IP network side is made possible by the provision of IP-PAD cards in the PIR.
A single system can support up to a maximum of 16 8RU PIR’s.
1RU POWER UNIT
A 1RU 19” Rack mountable Power Unit that feeds 48 volts directly into the onboard DC power package has been coupled the 8RU PIR to allow for maximum concentration of line and trunk packages and to alleviate any power limitations.
The power Units come with 2 slots that are designed to accommodate either 1, or for a redundancy option, 2 hot pluggable 48v Rectifier modules.
Fit a safety cover or to block access to the second slot of the Power Unit if the second rectifier module is not fitted.
IP MEDIA DEVICES
The serveris capable of supporting a range of IP and SIP Devices as well as IP and SIP terminals. PSTN and ISDN Media Gateways (MG),Analogue Media Converters (MC), and voice conferencing servers (VS)devices in most cases are common between the U-IPX and the server. This allows options for an IP deployment which can be on either asingle site LAN or over a National WAN.Theycan be in the form of a blade that slots into a 1RU 19” rack mounted MPC but can also be available in a standalone box.
8 PORT ANALOGUE MC
Media conversion between conventional Voice Data (MC-connected conventional terminal side) and Internet Protocol (LAN-side)is provided by the MC8 blade. By using this converter, up to 8 analogue telephonescan serve as IP stations under the control of the server system. Media Data (voice/ fax) is sentand received directly between IP terminals (MC-to-MC, MC-to-UNIVERGE desktop IPextensions, etc.) in Peer-to-Peer connection.
The 8MC blades can mount in either side or both sides of a 1RU Multi-Purpose Chassis (MPC). With a 2nd8MC blade mounted into a single MPC, the offering becomes a single 19” rackmountable 1RU 16 port media converter.Analogue telephones or fax machines can be connected to any of the eight front accessible modular RJ45 jacks which comes with the 8MC Card
ISDN PRI MG
The ISDNPrimary Rate Media Gatewayis a blade which interfaces between the public ISDN and the IP network. It provides an efficient connection for up to 30 trunksdepending on the configuration of the server. Up to 32 MG-PRI Media Gateways can be supported by each server.
The SCA-PRI Media Gateway under control of the server can also act as a QSIG E1 trunkinterface into the IP network.
4 PORT ANALOGUE MC/2 PORT MG
The MCMG blade is an 4 port Media convertor (MC) and 2 port Media Gateway (MG).
The 4 port Media Converter (MC) interface providesmedia conversion between conventional Voice Data (the MC connected terminal) and the Internet Protocol (LAN-side).
The 2 port Media Gateway (MG) is the interface between public carrier network (PSTN) and the Internet Protocol (LAN-side)
In the case of power or Network failure, this device can provide Power Failure Transfer (PFT) which connects the PSTN lines and Analogue terminals directly.
CONFERENCE SERVER MG
The VS-32 Conference Server blade’s main function is to provide multi-party conference call ability between IP Devices and IP stations for calls over the network. It also sports multiple features such as; multi-party Conference, Announcement, andan External Hold-Tone feature.
When required, the three-way Conference connection is availablefor UMS call recording which allows the conversation between two parties to be recorded.
As a remote deployment when a network failure occurs, the VS-32 Conference Servercontinues to provide the Announcement feature, External Hold tone feature, and Conferencefeature in conjunction with the activated remote survivable server (SR-MGC).
SIP TRUNK MG
Multi-service and reliable VoIP networks using SIP as defined by IETF are made possible by the MG SIP blade (SCA-16SIP). It supports up to 16 trunks. Features include routing, call setup, transferring feature messages, and authentication.
A 1RU MPC that can be installed into the 19” rack allows for various MC/MG options. 1 or 2 Media Converter/Media Gateway cards or SIP blades can be installed into the MPC.
