<p>PROBLEM TO BE SOLVED: To distribute a load of an incoming call impartially in a hunt group by setting a link to all terminal lines whose HDLC link is disconnected in a hunt group facility. SOLUTION: When a packet exchange PS2 receives an incoming call to a representative number (b), the call is distributed to a terminal line set by an HDLC(High Level Data Link Control) link in an incoming call hunt group and sends an SABM(Set Asynchronous Balanced Mode) to terminal lines whose HDLC link is disconnected and whose terminal class is defined to make HDLC link setting and a succeeding incoming call is uniformly distributed in the hunt group. Then the SAMB is sent to terminal lines whose HDLC link is disconnected but sending positively the SAMB in the hunt group and when the setting of HDLC link is successful, the succeeding incoming call is distributed to each terminal line.</p> |
