About Child Signal Termination Points

A child signal termination point represents a child signal level in a signal structure, such as the DS0 signals in a DS1 signal structure. Although you can create the specifications in any order, it is generally a good practice to begin with the child signal termination points and then move to the parent. Having the child termination points already created makes it easier to create the parent termination points. When you configure a child Pipe Signal Termination Point specification, you define the capacity unit amount, unit of measure, and number of child signals.

You can optionally define compatible signals. These are Pipe Signal Termination Point specifications that define capacity unit amounts that the signal can support even though they are not an exact match for the main capacity unit amount. For example, you can configure, a SONET STS1 51.840 Mbps channel to support a DS3 facility at a rate of 44.736 Mbps in addition to an STS transmission facility of exactly 51.840 Mbps.
