CHAPTER 7 THE E1 AND T1 INTERFACES, WITHOUT SIGNALING

The menus relating to configuration of the E1 and T1 interfaces without signaling are given in this chapter. T1 is a standard used in the United States, Canada, and Japan. It has a clock speed of 1.5MHz and has 24 channels of 64K each. One of the channels is reserved for signaling when ISDN/PRI is used. E1 is a standard used in Europe and many other countries. It has a clock speed of 2MHz and has 32 channels with two reserved for signaling. Aside from this, there are few differences between the two standards in terms of configuration.

The Controller menu tree for the PR4000 (for Signaling Mode = None) is shown in figure 7.1
