NOTES:

1. Unlike the DSX–1 template, which is specified at the cross–connect point, the CEPT (2.048 MHz) template is

specified at the transmit line output.

2. The template shown above is normalized. The actual pulse height is cable dependent and is specified in

Table 3.

3. The corner points shown below are joined by straight lines to form the template.
