Cabling
This chapter describes BSR, SPR, and IDR Ethernet and serial cabling.
6.1. BSR-to-BSDU Cabling
The BSR interfaces with the provider’s backbone through the BSDU (or SDA). The BSR connects to the BSDU
using a CAT 5 cable. (The BSR-to-SDA cabling is the same as SPR-to-SDA cabling. See Section
6.2.)
