1.2 NaturalFax Performance on AG Boards

The following section summarizes NaturalFax performance on AG boards. Configurations are presented for the following applications: Maximizing the number of ports running voice and fax transmit operations Maximizing the number of universal ports (each port can run any voice or fax function) Supporting all available ports on a board
All of the configurations presented in the following tables have been load tested with NMS speech encoding for voice functions and without echo cancellation. In some configurations not all ports may be used due to insufficient DSP resources. If too many operations are performed, the event NFXEVN_SESSION_DONE is returned with the reason code CTAERR_OUT_OF_RESOURCES.
If your application requires a different use of DSP resources (e.g., adding an echo canceller or using different speech encoding), you may achieve different performance results. You should test your application carefully with the expected number of ports and functionality to ensure you have sufficient DSP resources. Refer to Appendix B of the AG Access Installation Manual for further information on ADI service DSP requirements. Refer to Appendix F of this manual for further information on NaturalFax DSP requirements.
In the following tables, the functions supported on each board are summarized as Voice (voice, DTMF detection, tone generation, etc.), Fax Transmit, and Fax Receive.

1.2.1 Maximizing the Ports Running Fax Transmit

The first table shows the maximum number of fax transmit operations allowed on each AG board. In these configurations, fax receive cannot be run on any of the ports. Maximum Fax Transmit Operations per Board Board # of Ports Restrictions mu-law Config File a-law Config File AG-8/80 8 ports none ag8fax.cfg ag8faxa.cfg AG-T1 24 ports Voice and Fax Transmit only agt1fax.cfg AG-E1 30 ports Voice and Fax Transmit only age1fxtx.cfg AG-24+ 24 ports Voice and Fax Transmit only ag24fax.cfg ag24faxa.cfg AG-30 30 ports Voice and Fax Transmit only ag30fax.cfg ag30faxa.cfg AG-48 48 ports Voice and Fax Transmit only ag48fxtx.cfg ag48fxta.cfg AG-60 60 ports Voice and Fax Transmit only ag60fxtx.cfg ag60fxta.cfg AG-T1 V2 24 ports none agt1fax.cfg AG-E1 V2 30 ports none age1fax.cfg

AG-T1 V2	24 ports	none	`agt1fax.cfg`
AG-E1 V2	30 ports	none		`age1fax.cfg`

The next table shows the configuration which allows for the maximum number of universal ports. Universal ports can run any voice or fax operation. In all configurations (except the AG-8/80), some of the ports cannot be used. Maximum Universal (Fax and Voice) Ports per Board Board # of Ports Restrictions mu-law Config File a-law Config File AG-8/80 8 ports none ag8fax.cfg ag8faxa.cfg AG-T1 20 ports Remaining ports must be unused agt1fax.cfg AG-E1 20 ports Remaining ports must be unused age1fax.cfg AG-24+ 20 ports Remaining ports must be unused ag24fax.cfg ag24faxa.cfg AG-30 20 ports Remaining ports must be unused ag30fax.cfg ag30faxa.cfg AG-48 40 ports Remaining ports must be unused ag48fax.cfg ag48faxa.cfg AG-60 40 ports Remaining ports must be unused ag60fax.cfg ag60faxa.cfg AG-T1 V2 24 ports none agt1fax.cfg AG-E1 V2 30 ports none age1fax.cfg

Based on the configurations in the preceding table, you can determine which combinations of boards meet your system requirements.
For example, for an application requiring two full T1 spans running fax transmit and receive, you would need two AG-T1 boards and an AG-8/80 DSP board. The AG-T1 boards each provide 24 telephone channels and DSP resources for 20 ports of fax and voice operations. The AG-8/80 DSP board provides the DSP resources for 8 additional fax and voice ports.

Maximum Universal (Fax and Voice) Ports per Board
Board	# of Ports	Restrictions	mu-law Config File	a-law Config File
AG-8/80	8 ports	none	`ag8fax.cfg`	`ag8faxa.cfg`
AG-T1	20 ports	Remaining ports must be unused	`agt1fax.cfg`
AG-E1	20 ports	Remaining ports must be unused		`age1fax.cfg`
AG-24+	20 ports	Remaining ports must be unused	`ag24fax.cfg`	ag24faxa.cfg
AG-30	20 ports	Remaining ports must be unused	`ag30fax.cfg`	ag30faxa.cfg
AG-48	40 ports	Remaining ports must be unused	`ag48fax.cfg`	ag48faxa.cfg
AG-60	40 ports	Remaining ports must be unused	`ag60fax.cfg`	`ag60faxa.cfg`
AG-T1 V2	24 ports	none	`agt1fax.cfg`
AG-E1 V2	30 ports	none		`age1fax.cfg`

The last table shows the configurations for supporting all ports on a board. In some configurations, fax operations are only allowed on a subset of the ports: Supporting All Ports per Board Board # of Ports Restrictions mu-law Config File a-law Config File AG-8/80 8 ports none ag8fax.cfg ag8faxa.cfg AG-T1 15 ports 9 ports Voice, Fax Transmit, Fax Receive Voice only agt1fax.cfg AG-E1 4 ports 26 ports Voice, Fax Transmit, Fax Receive Voice only age1fax.cfg AG-24+ 15 ports 9 ports Voice, Fax Transmit, Fax Receive Voice only ag24fax.cfg ag24faxa.cfg AG-30 4 ports 26 ports Voice, Fax Transmit, Fax Receive Voice only ag30fax.cfg ag30faxa.cfg AG-48 30 ports 18 ports Voice, Fax Transmit, Fax Receive Voice only ag48fax.cfg ag48faxa.cfg AG-60 8 ports 52 ports Voice, Fax Transmit, Fax Receive Voice only ag60fax.cfg ag60faxa.cfg AG-T1 V2 24 ports none agt1fax.cfg AG-E1 V2 30 ports none age1fax.cfg

Based on the configurations in the preceding tables, you can determine which combinations of boards meet your system requirements.
For example, for an application supporting a full T1 span, your application may use any combination of voice and fax functions on the first 15 ports on the AG-T1 board. Your application must restrict the remaining 9 ports to use only voice functions to ensure that enough DSP resources are available for each port.
