5. ed modes of operation For this reason wanpipel conf is need to configure a WANPIPE TDM Voice driver to load the correct card and attach the hardware T1 E1 port to correct ZAPTEL SPAN There is an added benefit to this configuration User can specify exactly which T1 E1 PORT is bound to which ZAPTEL SPAN Ona single PORT SPAN system this might not be a big deal however on systems with 16 PORTs SPANSs it can prove difficult to figure out which SPAN belongs to which port if PORTs SPANs are autoconfigured With Wanpipe drivers Use the Back button of your browser to return to the main thread
6. elect lt BACK gt Protocol and Interface Setup Configuration for each individual timeslot is the same as standard wanpipe configuration A104D Mixed HW Echo Cancelled Voice amp Wan Data Configuration No issues From wanpipe beta2 2 3 4 tgz release on this problem has been solved Data channels and Voice channels can be mixed and interchanged Configuring Zaptel and Asterisk Zap Channels Wanpipe uses Zaptel to interface with Asterisk so it is necessary to add parameters for zaptel etc zaptel conf and in Asterisk for Zap channels TI E1 Line lt gt Sangoma AFT Card lt gt Zaptel lt gt Asterisk PBX See Sample Zaptel Configuration Files Sample Zapata Configuration Files Why is wanpipe conf file needed along with Zaptel conf A common question received by Sangoma Tech Support is Why does one need wanpipel conf file when zaptel conf defines all the hardware and span information already Is wanpipel conf simply a duplication of already existing information Answer Wanpipe is a SUITE of device drivers that run over AFT series cards 1 Wanpipe SUITE contains WAN API and TDM Voice drivers 2 Wanpipe drivers support simultaneous channelized operation A group of channels 1 to 10 can run in TDM Voice mode ZAPTEL mode and another group of channels 11 to 24 can run WAN Frame Relay protocol all over a SINGLE TI E1 line Therefore TDM Voice mode is just one of the WANPIPE support

8. uses the following rules when parsing zaptel config file 1 Analog ports MUST be configured FIRST 2 T1 E1 Spans must be configured SECOND Furthermore if analog cards are used the analog FXO FSX ports must be assembled as per the zaptel conf order With A200 cards it is possible to switch FXO FXS order but this would break the autoconfig Finally after the autoconfig it is important to confirm that everything has been configured correctly and that commaond ztefg vvv works properly Top AFT A104 Wanpipe Configuration Run wanpipe configuration utility usr sbin wancfg Hardware Setup AFT Select Hardware Specify which AFT card installed from hardware probe After probing the hardware wancfg screen should show you in this example an A104 card Card Type gt A104 Physical Medium gt T1 Sepecify Line Type T1 or E1 Default is T1 Default configuration is complete Select lt BACK gt Protocol Setup Select Protocol TDM VOICE Configuration is complete Select lt BACK gt Interface Setup Skip First two options and leave them default Select SPAN Number 1 Unlimited The SPAN usually starts with 1 This option binds HW Port to a particular SPAN Select Override Asterisk Echo Enable AFT101 2 3 4 4d Default NO Setting this option to YES will DISABLE echo cancellation for this particular span ie ignore what is configured in zapata conf then set this option to YES
