6. number the more gain is added To decrease the signal level set the RX TLP setting to a negative value i e the more negative the number the more the signal level is decreased TX TLP The Transmit TLP setting controls the amount of gain or loss added to a voice signal from the CPE before it is encoded to digital PCM To increase the signal level set the TX TLP setting to a negative value To decrease the signal level set the TX TLP setting toa positive value Coding The Coding setting sets the PCM companding method used for a port The T1 environment uses m law coding and the E1 environment uses a law or a inv coding TC CGA The Trunk Conditioning during Carrier Group Alarm setting defines whether the FXS port should be forced idle or busy upon declaration of a Carrier Group Alarm CGA on the WAN link to which the port is assigned In most cases you should set this parameter to busy Ifa call is in progress when the CGA alarm is received the system will hold the call for two seconds drop it and then busy out the port to the attached PBX for the duration of the alarm Once the alarm clears the system will automatically place the port back in the idle mode making it available to the PBX LB The Loop back field lets you loop the port back toward the network and far end The dgt1 digital loop back sends the incoming digital DSO signal back to the far end without decoding it The anlg analog loop back sends the decoded a

8. s are assigned to the associated FXS and FXO voice ports at both ends In a point to point network the near end and far end FX card ports should both be assigned the same WAN port and time slot number Also make sure the other parameters such as the transmit and receive TLP s are set properly at both ends If the FXS card port parameters are correct at both ends and if the network is okay the trouble is isolated to the FXS card or the associated port Proceed with next step At the far end activate an analog loop back on the FX card port Send a 0 dBm digital milliwatt test signal toward the CPE at that end That signal will be substituted for the normal signal coming from the far end CPE it will be sent back to the CPE at your end via loop back path Check your CPE for this signal If itis present the far end CPE or cabling to the far end FX card is probably faulty Disable the loop back and test signal there and fix the problem If you still don t receive a signal go to step 2d At your end go to the FXS Card Main Screen and send a digital milliwat test tone 0 dBm toward the CPE and check the CPE itself If those items are okay replace the FXS card at your end If the FXS Coin Card is determined to be faulty replace it and return the faulty unit for repair to the location listed in your User Manual
