Chapter 1: Overview Echo-Cancellation Users connecting their TE120 series cards to the PSTN or other devices are likely to be placing calls that will result, at some point, in an unbalanced 4-wire/2-wire hybrid. The result of this hybrid is the reflection of a near-end echo to the calling party. Elimination of this echo is the responsibility of echo cancellation. The TE120 series cards, unless otherwise equipped, utilize Asterisk to perform software-based echo cancellation.

Chapter 3 Configuration The TE120 Series cards have a variety of configuration options. This chapter provides configurations for PRI, channel bank, E&M wink, and finally, data mode. These sample configurations are provided to assist you in familiarizing yourself with the flexibility of editing the configuration files to meet your specific needs. The list of possible configurations is too expansive to cover in this user manual. Release 2.2 Digium, Inc.
Chapter 3: Configuration Configuring Card Features Configure Zapata.conf, which is the layer between zaptel and Asterisk, to configure the essential card features. Switchtype: national: dms100: 4ess: 5ess: euroisdn: ni1: National ISDN 2 (default) Nortel DMS100 AT&T 4ESS Lucent 5ESS EuroISDN Old National ISDN 1 Echocancel: Echo Cancellation is enabled in zapata.
Chapter 3: Configuration Users of Digium's HPEC software have the following additional options: echocancel=512 (this sets 512 taps or 64ms) or echocancel=1024 (this sets 1024 taps or 128ms) Please note that HPEC consumes extremely high amounts of CPU MIPS that increase as the number of taps are increased. Audio quality issues may result from choosing a taps length greater than the server's ability to process the echo in real-time.
Chapter 3: Configuration Signalling: pri_cpe for CPE side. pri_net for NET side. If you have a T1 PRI, add these lines to the following lines of the sample file.
Chapter 3: Configuration Configuring T1/E1 Lines 1. Begin by opening the /etc/zaptel.conf. This is where the base configuration for your hardware is stored. If you did a make samples during the install, you can read through the commented example and edit it to your needs. Otherwise, continue following these instructions. 2. Next, configure your T1/E spans in the span definitions.
Chapter 3: Configuration Choose 1 to make the equipment at the far end of the E1/T1 link the preferred source of the master clock. Choose 2 to make it the second choice for the master clock, if the first choice port fails (the far end dies, a cable breaks, etc.). Choose 3 to make a port the third choice, and so on. If you have, for instance, 2 ports connected to the PSTN, mark those as 1 and 2. The number used for each port should be different.
Chapter 3: Configuration d4 or esf for T1 cas, or ccs for E1 ami or b8zs for T1 ami or hdb3 for E1 E1 can also have the extra flag CRC4 at the end for CRC4 checking. [,yellow] (optional) If the keyword yellow follows, yellow alarm is transmitted when Asterisk is not running. The following is a typical setup for a telco in the US: span=1,1,0,esf,b8zs In Europe: span=1,1,0,ccs,hdb3,crc4 3. Next, define the country zone. See the example configuration file for more details.
Chapter 3: Configuration First Example: Channel Bank The Channel Bank in this example has 24 FXS ports. In this configuration, the zaptel.conf is set for the card to provide timing to the channel bank and fxoks is set for 24 stations. Set zapata.conf to mirror the configuration with signalling=fxo_ks and define it for channels 1-24. T1 Channel Bank /etc/zaptel.conf: span=1,0,0,esf,b8zs fxoks=1-24 /etc/asterisk/zapata.
Chapter 3: Configuration Second Example: E&M Line To configure a span for E&M, the zaptel.conf must specify the span and the channel definition, while the zapata.conf specifies the signalling and incoming dialplan context for a group of channels. In the example below, the zaptel.conf shows the first span port configured to receive timing, with no line build-out (LBO), using ESF and B8ZS for framing and coding. The zapata.
Chapter 3: Configuration Third Example: PRI By setting the card to take timing in zaptel.conf, you acquire 23 b channels and voice channels, with channel 24 as the data transport. For Asterisk, define PRI_CPE so that it is the client side. Define the switch type you are connecting to as national. There are several options for the switch type including 5ESS, 4ESS, and NI1. You will then have 23 voice channels for Asterisk. PRI T1 /etc/zaptel.
Chapter 3: Configuration PRI E1 /etc/zaptel.conf: span=1,1,0,ccs,hdb3 bchan=1-15,17-31 dchan=16 /etc/asterisk/zapata.conf group=1 signalling=pri_cpe switchtype=euroisdn context=incoming channel=1-15,17-31 Fourth Example: Data Mode Data mode is a little different than the other options. The zaptel.conf is configured as follows: /etc/zaptel.conf span=1,0,0,esf,b8zs nethdlc=1-24 1. Uncomment the following line in zconfig.
Chapter 3: Configuration Build the data tools for Zaptel by executing: make data; make sethdlc-new Or, for kernels prior to 2.4.19 make data; make sethdlc make install 2. Load and configure your driver: modprobe wcte12xp ztcfg 3. Use sethdlc to bring up the interface: sethdlc hdlc0 cisco -or- for old style (make sethdlc instead of sethdlc-new) use: sethdlc hdlc0 mode cisco 4. Assign the interface an address: ifconfig hdlc0 192.168.0.1 netmask 255.255.255.0 5.
Chapter 3: Configuration Testing Your Configuration. 1. Load Zaptel drivers into the kernel using the program modprobe. The appropriate driver for the TE120 Series cards is wcte12xp. Use the following modprobe command: # modprobe wcte12xp # ztcfg -vv # dmesg ACPI: PCI interrupt 0000:01:00.
Chapter 3: Configuration 3. Execute the following Asterisk command to see if the span came up successfully. asterisk asterisk -vvvr Note: More detailed troubleshooting information is provided on http:// www.asterisk.org. Release 2.2 Digium, Inc.
Chapter 4 Troubleshooting This chapter provides frequently asked questions as identified from Digium Technical Support and possible resolutions. Multiple resources are available to obtain more information about Asterisk and Digium products. These resources are listed on page 52. What do the Status LED colors indicate? Green - Card is in-sync with the far end. Yellow - Card is synchronizing or is receiving a red alarm from the far end.
Chapter 4: Troubleshooting 2. Then type reload in the Asterisk console and call in. You should see the DID come in on your T1/E1 line. My D Channel seems to go up and down. Check to be sure you have set your timing parameters correctly. Also check the common causes of problems for a T1. See the Common Fixes for all cards, page 50. I have trouble dialing out. It seems that one type of dialing works (local, long distance, international) but another does not.
Chapter 4: Troubleshooting I am still having problems and the telco tells me it is my equipment. The first thing to do in this situation is to test your equipment. 1. Connect a loopback plug. (A loopback plug has pin 1 going to pin 4 and pin 2 going to pin 5.) Insert the plug into the span and wait for its LED to turn green. 2. Stop Asterisk and edit zaptel.
Chapter 4: Troubleshooting 3. Navigate to your zaptel source directory and type: make tests Followed by: ./patlooptest /dev/zap/1 60 The first argument in the patlooptest command is the device for the channel number you want to test. You should always test the first channel of a span. The second argument is the duration in seconds to run the test. This runs a pattern looptest for 60 seconds.
Chapter 4: Troubleshooting 2. Check to see if X windows is running by entering the following: ps aux|grep X If X windows is running, stop the application since it may cause a conflict with Asterisk. 3. Check to see if your IDE hard drives are running with DMA levels set. Advanced users can perform an hdparm on your hard drive interface. Use hdparm with caution as the man page states that hard drive corruption can occur when using incorrect settings.
Chapter 4: Troubleshooting How can I enable more features?
