摘要： PURPOSE:To obtain a simple time slot order storage system by inserting a training signal into a time slot and sending them out of an origination-side exchange side, and detecting the change rule of the time slot order among respective channels on a termination-side exchange and rearranging time slots of a received fast call according to the rule. CONSTITUTION:The origination-side exchange 2 inserts the training signal into (m) time slots corresponding to terminals A1-Am by switching a selector 222 to the side of a counter 221 by a training signal transmitting circuit 22. The termination-side exchange 4 receives them by a training signal receiving circuit 43 through a distribution stage channel 3 41 to detect time slots having the same number from the training signal group and recognize the rule of time slot rearrangement from the phase relation, thereby setting addresses from a memory 441 in an address generating circuit 443. Then, the selector 442 is changed over and a counter 444 generates a sequential address; and the selector 442 is changed and the readout order is restored according to the addresses stored in the circuit 443.

摘要： PURPOSE:To shorten the time from generation of a DMA transfer start request to start of DMA transfer by reading out directly empty buffer designating information without passing a main controller when the DMA transfer start request is generated and setting this information in a device itself. CONSTITUTION:When a buffer 31-i of a main storage device 3 becomes empty, a main controller 2 reads out the write address in a buffer designating queue 32 in accordance with a write address pointer 41. A start address Ai of the empty buffer is written in the buffer designating queue 32 in accordance with this read address, and thereafter, the write address is updated and is written in the write address pointer. When receiving a DMA transfer start request signal from a data receiving device 6, a DMA controller 5 reads out the read address in the buffer designating queue 32 in accordance with a read address pointer 42 and reads out directly the start address (for example, Aj) of the buffer in accordance with the readout address by DMA transfer and sets it in the device 5 itself. Thereafter, the read address is updated and is written in the read address pointer.

摘要： PURPOSE:To share one outgoing trunk among plural routes by providing a switching unit on the trunk line side of the outgoing trunk and connecting it to the trunk lines of the plural routes through the switching unit. CONSTITUTION:While the switching relay is not in operation, the outgoing trunk OGT is connected as the trunk of a route (o). On the other hand, when the switching relay is energized, the contacts rto and rto of a trunk block connector TBC are replaced by contacts rtn and rtn corresponding to a route (n) and the trunk line side of the OGT is connected to the trunk line of the route (n) by a t , so the OGT is connected as the trunk of the route (n). While the traffic intensity of the route (o) is high, a relay T is not operated and when the traffic intensity of the route (n) is high, the relay T is energized for route switching, so that the OGT operates as the trunk of a route with higher traffic intensity. Thus, the simple switching unit is provided between the outgoing trunk and trunk lines to facilitate outgoing trunks and trunk terminals in numbers, performing optimization.
摘要翻译：目的：通过在输出中继线的中继线侧设置切换单元，并通过切换单元将其连接到多条路由的干线，来分配多条路由中的一条出站中继线。构成：切换继电器不工作时，输出中继线OGT作为路由（o）的中继线连接。另一方面，当开关继电器通电时，中继块连接器TBC的触点rto <0>和rto <1>被对应于路由（n）的触点rtn <0>和rtn <1>所替代，并且 OGT的中继线侧通过<0>连接到路由（n）的中继线，所以OGT作为路由（n）的中继线连接。当路由（o）的交通强度较高时，继电器T不工作，并且当路由（n）的交通强度较高时，继电器T通电用于路由切换，OGT作为中继线的交通强度较高的路线。因此，简单的切换单元设置在输出中继线和中继线之间，以方便输出中继线和中继线终端的数量，执行优化。
