MGX-FRSM-HS1/B Cabling

The cable models come from the Cisco 12-in-1 series of cables. (See Table 2-10.) Each cable can have

a male or female connector at the far end. Also, the available clock sources depend on the mode. In DTE

mode, the clock source is either line or ST (ST is a wire in the cable). For DCE, the clock source is the

front card.

See Table 2-11 for the relationship between cabling and modes and Table 2-12 for part numbers.
