Typical Communications Performance Requirements for DS0 Based Circuits

* Relay dependent, see manufacturers requirements** Utility Defined depending upon function*** Protective Relaying Levels as defined by WECC, other governing bodies may have more restrictive requirements

Affected Technologies Provided by Carriers

• DS0 circuits• DS1 circuits• Frame Relay

This is not a one-step migration; it’s a two-step migration – both layer 1 (physical

transport) and layer 2 (protocol)
