ERL and SFRL Talking State
Echo-Return Loss (ERL) and Single-Frequency Return Loss (SFRL) performance 
is usually dominated by termination and/or loop input impedances. The system 
provides an acceptable level of echo performance if the ERL and SFRL are met.

2Hardware Configurations
The DEFINITY System supports a variety of configurations consisting of a PPN 
and up to 21 EPNs. In addition, the system may use a Center Stage Switch (CSS) 
consisting of one or two Switch Nodes. This chapter describes the PPN and EPN 
cabinets, and the configuration of carriers and circuit packs...

If the system has a Center Stage Switch, the E position holds a Switch Node 
Carrier. In a CSS system with duplicated PNC, the D position holds a Switch 
Node Carrier that duplicates the one in E position. In large systems requiring a 
CSS with two Switch Nodes, the second SN is located in an EPN cabinet, for both...
