Making Retimer Connections

The front panel of the E1 Retimer module and T1 Retimer module (shown in Figure 3-16) indicates the input and output connections for a typical installation. Side 1 of the Retimer provides 3R (Re-shape, Re-amplify, and Re-time) for the E1 or T1 signal to a client Network Element.

Figure 3-16. Front Panel of the T1 (wire-wrap) and E1 (BNC) Retimer Modules

Figure 3-17illustrates a sample schematic for connecting a Retimer connected to both sides of a DSX-1 panel in a Central Office.
