More than two HLCs
If there are three or more HLCs present in your switch, the information in the
preceding paragraphs applies to the cards on either end of the daisy chain, the
MMI end and the SDI end, for maintenance access. The cards that are not on
either end are called intermediate cards. All intermediate cards are not directly
connected to either the MMI or SDI and require different DIP switch settings
from the cards on each end. For more details, see "Intermediate cards" on page
39.
The following illustration shows the general cable configuration of a multiple-
HLC site.

Note: This illustration shows three HLCs in a daisy chain to demonstrate the
pattern of cabling connections required for a successful daisy chain. Meridian
HomeOffice II systems can involve daisy chains of from 2 to 32 HLCs.
