Title: Exchange
Inventor: KONAKA TOSHIKI
IPC: H04M3/00
Filed: 1990-07-09
Abstract: PURPOSE:To use a band for 24 sets of B-channels even at a fault of other line by allocating D-channel information to a frame header of a primary group interface line when a fault of other line is detected. CONSTITUTION:When a fault takes place in other line 15 on which D-channel information of its own line 13 is superimposed, an exchange 11 allocates an area from/to which the D-channel information is sent/received to m-bits on a primary group interface line 13 being its own line. Thus, the primary group interface line 13 always uses all bands as a B-channel. Moreover, the D-channel information is allocated to a frame header of the primary group interface line and always sent and received in the line with less call control information using the band of 24 B channels at all times for a large capacity file transfer or the like. Thus, the entire band of the primary group interface line is always used as B channels independently of the presence of the other line.
