↲
┆84┆CIRCUIT I consist of maximum 7 slaveterminals and one↓
┆19┆┆89┆┄┄masterterminal, all terminals from the RC850 serie. If ↓
┆19┆┆89┆┄┄the master is an RC890 there can be a total of 32 ↓
┆19┆┆89┆┄┄connections.↲
↲
┆84┆CIRCUIT II shall have an RC3900 as master, and can have ↓
┆19┆┆89┆┄┄up to 32 connections for terminals from the RC850 serie.↲
↲
┆84┆The DUAL-CIRCUIT line is established as a fixed twisted ↓

┆19┆┆89┆┄┄for each receptacle.↲
↲
┆84┆The master is connected to modem equipment if any, and ↓
