Operational Features
Fax Ports Per Chassis
The Advanced Media Server is available in 4, 8 and 16 fax port configurations.
Operational Capability
Each Advanced Media Server automatically boots up and the application starts (or optional capability to Start the Server after receiving a command from the GMS). The administrator also has the option of restarting the Advanced Media Server manually, either locally or remotely.
Monitoring
Fax Port Monitoring
All the fax ports of an AMS can be monitored at one module screen called Port Monitor Screen. It lists the Port Status of all the fax ports in the AMS listed by port number and allows monitoring of Port Number, Line State whether Onhook or Offhook, Status, Number Called, CSID, Start/End Time and Last Error. It also displays graphically the configuration of the fax port as inbound, outbound or bi-directional. The Onhook and Offhook of a port are represented by a telephone handset that is displayed graphically.
WAN Monitoring
All the activity on the WAN can be monitored at the WAN Monitor Screen, which displays port status of all the WAN ports in the AMS listed by port number. It allows monitoring Port Number, Line Status, Destination Address (Destination AMS), Job ID, Start/End Time and Last Error. The WAN ports can be configured as inbound, outbound and bi-directional, which is displayed graphically.

Channel Status
Channel Status displays the port mapping, current status or state, and type of port of all the ports in the AMS. The Channels can be enabled or disabled for individual fax ports in the AMS. This feature makes it convenient to disable a fax port, if experiencing problems with that particular port without a server down.

Remote Operation
The Advanced Media Server is fully operational from a remote location through a 'dual serial port modem interface' or over a WAN. As a remote subscriber, you can perform all Advanced Media Server functions, including Advanced Media Server reboot, application start/stop, configuration, file transfer, and diagnostics/troubleshooting actions. The modem interface also lets you upload and download all Advanced Media Server configuration files, including DTMF/telephony parameters, subscriber command syntax, error logs, and transaction/port performance statistics.
Independent Advanced Media Server Operation
If the GMS is unavailable (for example, network busy or off-line), the Advanced Media Server continues operations by storing faxes and transaction status until GMS connection is fully re-established. Once this connection is re-established, the faxes and transactions are sent to the GMS.
Comprehensive Error Handling
The Advanced Media Server records low-level errors (such as T.30) in a local database. The transactions and errors can also be recorded on a central, remote database server.
Data Transfer Rate
Data is transported over the WAN through TCP/IP data networks at baud rates of 2.4K to 382KBps, and at 10Mbps over Ethernet 10BaseT (this is dependent on traffic on the WAN and also a function of number of collisions).
Line-Service Types
Each telephony port supports several common line service types and dial plans, including toll-free, PBX, local, and long-distance services.
Disk Usage
Each Advanced Media Server is configured with a minimum of fifty (50) megabytes of available document storage for each fax port. You also have the option of configuring additional storage per port. The disk status bar displays the current disk statistics of the AMS and Pending Documents (number of fax jobs waiting to be processed) High and Low marks can be assigned for the disk in the configuration. As soon as the disk reaches the high water mark, the system stops receiving new jobs so that the hard drive doesn’t run out of disk space.

Floppy-Disk Drive
Each Advanced Media Server is equipped with one 3.5" 1.44 MB floppy-disk drive, which is required for operations involving initial installation, configuration, file transfer, and troubleshooting.
Fax-Related Features

Each Advanced Media Server port operates independently, yet simultaneously, with all other Advanced Media Server ports configured.
Each port can be configured as inbound or outbound. Each port can be enabled or disabled on the Advanced Media Server. The Advanced Media Server telephone interface supports Loop Start interfaces.
The Advanced Media Server is fully compliant with CCITT T.4 and T.30 recommendations (1988) for Group 3 facsimile transmission, including, but not limited to, the following items:
Page width (A4, B4)
Page length (unlimited)
Resolution (standard, fine)
Generation of CNG
Transmission (send/receive) of CSID
The Advanced Media Server is able to dial using DTMF (Dual Tone Multi Frequency) or Pulse (10 and 20 pps) signals, depending upon the telephone network to which it is connected.
When attempting to connect to a destination fax device, the Advanced Media Server is able to differentiate between the following signals:
Dial tone
No dial tone
Network congestion (fast busy)
Busy
No audio energy detected
Ringback detected
No Ringback detected
Answertone detected
No Answertone detected
Loop current failure after connection (no energy)
Non-G3 modem answered
Voice/recording answer detected (default)
The Advanced Media Server controls signal detection and processing to facilitate flexibility in call progress processing in different countries. Call progress is conducted on OAZ's DD/4 fax board.
In the event of AMS unavailability (for instance, an AMS error such as disk space allocated for AMS is full), the AMS can busy-out all inbound ports.
The AMS maintains a local delivery table, which is downloaded from GMS. Any fax that is received by the AMS and has a destination number that matches its local delivery table will be delivered from that AMS.
Configurable Features
Retry Strategy for Failed Transmission
The scheduling of retry strategy for failed transmission is set with the Maximum Retry parameter which allows to set the maximum number of times the AMS will try transmitting a particular fax job. And the Retry Delay parameter determines the number of seconds between retry attempts during the first, second and the third hours.

Allocation of Fax Ports to Fax Broadcast Jobs
The Broadcast Ports (%) option allows to allocate a percentage of fax ports that will send fax broadcast sub-jobs. If there are more sub-jobs in the fax broadcast job than there are available broadcast fax ports, the extra jobs will be placed in the Pending Documents queue until a broadcast fax port becomes available. This is to ensure that the AMS will have fax ports available for single fax job traffic while it is processing fax broadcast jobs.
WAN Throughput
GMS allows one to eight WAN connections at a time. While one connection is required, additional connections will help improve throughput. This will allow the server to support more than one communication session at a time, ensuring less network bottlenecks.
Dialing Codes
The Advanced Media Server allows to set the dialing Country and City codes, where the AMS is located. It also allows to set Access Codes for long distance and International calls.

Fax Page and its Quality
The AMS can monitor inbound fax page size and reject the document if the page exceeds the following configuration parameters:
K-per-page
Inches-per-page
Mins-per-page
N-page
Percent-errors
Burst-errors
Total-errors
The AMS also can reject an inbound document based on image quality (Consecutive, total, and % error scan lines). All criteria are based on configuration parameters.
Maximum Flexibility in Communicating
The Advanced Media Server supports a range of values used during transmission and reception that allow for maximum flexibility in communicating different document types to and from different types of fax devices.

Maximum Document Size
The Advanced Media Server can send, receive, and store up to 255 pages of facsimile data per document, per port.
Subscriber-Related Features
The following information describes the subscriber-related functions of the Advanced Media Server.
Subscriber Access
Once a phone call is received, the Advanced Media Server generates tone signals over a telephone interface (parameters: frequency and duration) to verify service connection. Once service is connected, the Advanced Media Server detects Dual-Tone-Multiple-Frequency (DTMF) signals from the subscriber/subscriber. Authorized DTMF signals correspond to the following standard DTMF tone-pad keys:
Digits 0 though 9
* (Asterisk)
# (Pound)
Up to 128 DTMF signals can be entered per transaction, dialed either manually or automatically. After validation of the subscriber/subscriber, the Advanced Media Server either prepares to receive a fax document or terminates the call. Before call termination, the Advanced Media Server generates tone signals to verify call completion.
Local Subscriber Validation
The Advanced Media Server can receive DTMF input. Validation is done prior to receiving fax image data from a subscriber. While the Advanced Media Server is performing validation locally, the AMS maintains the link with the remote fax device. Once the AMS validates the Subscriber input, the Advanced Media Server enters into a
fax receive state in order to accept the incoming fax pages.
Subscriber Service Type
Service Type information is an optional part of the DTMF input that is received by the AMS from a Subscriber. The subscriber can specify the Service Type of a particular fax job. The three service types are, point-to-point fax to one or more fax numbers or broadcast list, obtain a report of your broadcast list or status report (daily journal). A subscriber can also assign feature options with these service types. The feature types are: If the subscriber selects to receive an acknowledgment, the acknowledgment is sent to the subscriber irrespective of success or failure of a particular fax job. The acknowledgment can be received at any other forwarding address other than the address registered in your subscriber profile. The other feature options are Deferred Delivery, Delivery Time Limit, Delivery Notification, Forwarding Address and Daily Journal. The Service Type string consists of the following:
