OC-12 Ring Configuration (DS1/EC-1 Low-Speed
Interfaces)
3
Figure 3-7 shows an OC-12 configuration using DS1/EC-1 low-speed interfaces.
Interface to the low-speed shelf is made through the IS-3 (or OC-3) circuit packs,
one service and one protection pack per interface. The IS-3 circuit packs replace
the OLIU circuit packs in the main slots on the DDM-2000 OC-3 shelf. This
configuration supports a high-speed OC-12 interface with 84 DS1 terminations
per DDM-2000 OC-3 shelf, up to a maximum of 336 DS1 terminations.
