System 85 DS1/DMI to System 75 DS1/DMI — Colocated Arrangement

Permitted Cabling Combinations

Using cable GR-380:

ANN11C/D/E ↔[335-337] ↔ GR-380 ↔System 75

ANN11C/D/E ↔[367-369] ↔ GR-380 ↔System 75

Using old cable groups:

Connections using cable group 357 will not work.

Using new cable groups:

ANN11C/D/E↔ [367-369] ↔ 370 ↔ System 75
