Id entify the OC-3/STM-1 p orts on the ATM switc h that have DEFINITY p ort networks attac hed . nBe aware that c ustomers may use other p orts on the ATM switc h for ap p lic ations unrelated to DEFINITY (LAN traffic or multimed ia ap p lic ations, for examp les). nThese other applications may manifest themselves in the output of the troub leshooting c ommand s you run on the ATM switc h. DEFINITY p ort networks must be id entified by their ATM switc h p ort numb ers. NOTE: The following examples show DEFINITY p ort networks c onnec ted to ATM switc h p orts A1.1 and A1.2. 1.Does the TN2305/TN2306’s YELLOW LED flash 100 ms on and 100 ms off, indic ating a loss of sig nal on the fiber? Rec all that the TN2305/TN2306 d etec ts c ontinuity p rob lems with either the transmit (b ottom) or the rec eive (top ) fib ers. If the fib er shows a loss of signal, refer to the “ Fiber Fault Isolation Proc ed ure” in DEFINITY ECS Maintenanc e for R8r. 2. Is the ATM switc h port’s LED ind ic ating a loss of sig nal on the fib er? Note that the ATM switc h may d etec t c ontinuity p roblems only with the rec eive fib er; the state of the transmit fib er mig ht not b e d etec ted . 3. Refer to your ATM switc h’s q uic k referenc e g uid e for troub leshooting commands. Possible causes. Check the following list for possible c auses. nThe fib er is d isc onnec ted from the ATM switc h and /or the TN2305/TN2306 circuit pack. nThe transmit and rec eive fib ers are swap p ed at the ATM switc h or the TN2305/TN2306 c irc uit p ac k (b ut not b oth). nThere is a b reak in the fib er. nThe TN2305/TN2306 is not transmitting a c arrier (not inserted , not p owered , or not ad ministered ). See the ATM-EI or ATM-TRK maintenanc e ob jec ts in DEFINITY ECS Maintenanc e for R8r. nHard ware safety interloc ks on optic al transc eivers may c ut transmitter p ower if no c arrier is rec eived , so lac k of a rec eive c arrier c ould ind ic ate a transmitter p rob lem at the same end .

You may need to re-ad minister the ATM switc h p ort b oard s. Refer to your ATM switc h’s q uic k referenc e g uid e for further information. Recommended Action. 1. Plug in, swap , rep air, or rep lac e the fib er as nec essary. 2. Verify that the port c irc uit p ac k is c omp letely inserted . SONET/SDH layer Are SONET/SDH frames reaching the ATM switch? Is the ATM switch port’s LED indicating no cell traffic? nChec k the transmit and rec eive c ell c ount field s. Eac h field ’s values should b e inc reasing if the TN2305/TN2306 is ac tively send ing and rec eiving c ells to and from the ATM switc h. nChec k for SONET/SDH layer alarms, LOP, LUF, and so on. nIf neither field is inc reasing , the ATM switc h p ort may be d own. Verify that the ad min status is up . nIf the rec eive c ell c ount is inc reasing b ut the transmit c ell c ount is not inc reasing , this may b e b ec ause the p ort was ad ministered with no UNI signaling. Ensure that signaling is UNI3.1. nAlthoug h the error c ounters may not b e zero, they should not b e larg e either c omp ared with the rec eive and transmit c ell c ounters. If the c ounters are larg e and inc reasing , c hec k the fib er integ rity. Make sure the fib er p airs are sec urely p lugg ed into b oth the TN2305/TN2306 c irc uit p ac k and the ATM switc h. nIf the fib er has b een p ulled and reinserted as p art of fault diag nosis, the nonzero loss of sig nal error c ounter may b e c orrec t. Q.SAAL (data link) layer Are ATM signaling messages reaching the ATM switch Call Control? NOTE: If the TN2305/TN2306 c irc uit p ac k is not c onnec ted to the ATM switc h at the Q.SAAL p rotoc ol layer, then no rep ort is d isp layed . 1. If the port of interest is not c onfig ured for UNI sig naling , then the p ort was ad ministered for no UNI sig naling . Verify that sig naling is UNI3.1. 2. If the p ort of interest was ad ministered for UNI3.0 sig naling , verify that sig naling is UNI3.1. 3. Chec k to see if the TN2305/TN2306 c irc uit pac k is ac tively send ing and rec eiving Q.SAAL Protoc ol Data Units with the ATM switc h.
DEFINITY ECS Release 8.2 ATM Installation, Upgrades, and Administration 555-233-124 Issue 1 April 2000 Troubleshooting 6-35 Troubleshooting ATM-PNC 6 Q.93B (network) layer Are connection requests being received by ATM switch call control? NOTE: If there is no c onnec tion b etween the TN2305/TN2306 c irc uit p ac k and the ATM switc h at the Q.93B p rotoc ol layer, then no rep ort d isp lays. 1. Chec k the p ort of interest. If it is not c onfig ured for UNI sig naling , then the p ort was ad ministered for no UNI sig naling . Verify that sig naling is UNI3.1 2. The c onnec t, setup, and release message c ounters should b e a nonzero numb er if the ATM switc h is hand ling Q.93B p rotoc ol layer messag es sent b y the PPN and EPN. They may not inc rease during troub leshooting unless c alls are b eing mad e b ec ause the PPN initially sets up c ontrol c onnec tions to the PPN and then sets up talk p ath c onnec tions as needed. 3. Check to see if c onnections are being rejected. The error may be on the PPN p ort even thoug h the EPN p ort is the one misb ehaving and vic e versa. 4. Type display errors and press En t e r. 5. Set the Error List field to errors and Category field to PNC on the input sc reen (Screen 6-14 ) and p ress En t e r to display any c ause c od es (see Table 6-11 ) returned from the ATM network to a TN2305/TN2306 c irc uit p ac k on the PPN (and to a TN2305/TN2306 c irc uit p ac k on an EPN). This is suc c essful only if the links between the PPN and the EPN remain up so that the messag e from the EPN is log g ed.
