Table 4-2. DDM-2000 OC-3 Shelf Circuit Pack Codes
Notes:
1. Maximum per shelf is based on Point-to-Point applications only.
2. Minimum functionality, as defined here, includes protection switching, thus protection cir-
cuit packs are included.
† An even number of MXRVOs, DS3s and/or EC-1s must be installed to accommodate pro-
tection switching. Also, the sum of MXRVOs, DS3s and EC-1s cannot exceed six.
†† For every function group equipped with MXRVOs, between two and eight DS1s must be
installed.
* Unequipped DS1 service slots in an in-service low speed group MUST be terminated with
177A retainers. The sum of DS1s and 177As MUST total eight per function group to
accommodate protection switching.
‡ For 21 and 22 type OLIUs, minimum and maximum circuit pack quantities are determined
by network topology. 21 type OLIUs are not used with ring Releases 7, 9, 11 and 13.
27G-U OLIUs are used only with Releases 9, 11 and 13 shelves configured as DDM-
2000 FiberReach hosts.
# A maximum of 3 BBF8 circuit packs can be used per function group.
