一、S1240的软件概况程控交换机软件设计的目标之一是要使其能适应今后的发展。这主要是指当功能强、价格便宜新的硬件(如存储器、处理机、电话交换设备等)出现而取代原有硬件时,交换机的软件能在不修改或少修改的情况下与之适应;当要求程控交换机增加新的业务时,其软件亦能方便地增加。S1240软件设计的目标同样是如此。在S1240机中,为了达到这个目标,采取了下列三个设计方法。
A, S1240 Software Overview Program-controlled switch software design goal is to make it to adapt to the future development. This mainly refers to the switchboard’s software can be adapted with little or no modification when the powerful and cheap new hardware (such as memory, processor, telephone switching equipment, etc.) appear instead of the original hardware; When required to program-controlled switches to add new business, its software can also be easily increased. The same is true of the S1240 software design goals. In the S1240 machine, in order to achieve this goal, has taken the following three design methods.
