EXECUTIVE SUMMARY
By loading GSM BSC 08A IP-A18the behavior of the node will improve in several areas: System robustness has been improved by: - The L2TP has now been improved to handle corrupt payload frames, which could lead to RP restart (ref. 109 22-APT 210 09/216-2365) (IP-A18) - Correcting several faults in the GARP2 OS, causing for example GARP2 RP restarts or very high load in GARP2E RPs (ref. 10922-21220/7-1508). (IP-A18) - Correctinga fault that could cause a small restart during RP function change (ref. NNAAH-6041). (IP-A17) - Correcting a fault that could cause a stop at restart phase 8 (ref.NNAER-0903). (IP-A17) - Avoiding a fault which could lead to pointer too large in RQUCD (ref. NWAAH-6060). (IP-A17) - A fault has been corrected to avoid a small restart due to pointer to large (ref. RWAYJ-0825). (IP-A17) - Correctingan error in the routing algorithm for SGSN in pool, which could cause the SGSN node to be overloaded and GPRS services to be denied (ref. 10922-APT21009/216-2309).(IP-A17) - A fault has been corrected to avoid a APPLERR in block RTGPHDV at H’10D8 and avoid a cyclic restart on the BSC (ref. NNAER-0789). (IP-A16) - A fault has been corrected to avoid IAS timer to running for Connection Section (CS)which is IDLE. This can lead to reported

event FC 1102 in Syrip Survey (ref. NNAYJ-0867). (IP-A16) - Improved load handling when a large number ofRESET messages are received from Blade Cluster MSCs (ref. NWAAH-5965) (IP-A16) - Avoiding a potential small restart in block RNSDCCH (ref. NWAAH-5978). (IP-A16) - Avoiding a small restart, due to pointer too large in RTGPHDV (ref. NWAER-0600). (IP-A16) - Avoiding variable CCLOCK to have even values which lead to too long scanning in time supervision mechanism due to finding all idle individuals(ref. NWAER-0791). (IP-A16) - Avoiding a pointer to large in block SCTP (ref. RWAVN-0107) (IP-A16) Command/Printouts: - A fault has been corrected to avoid command RRPCP:RPINFO to produce no printout and cause Pointer Too Large (ref. NWAER-0935). (IP-A18) - A fault has been corrected to avoid hanging IO terminal when mounting a volume to store output files on RP tapes (re. Z02BL-1139) (IP-A18) -...
