**Notes:**

**^(1)^**Acceptance Classification: C-Conditionally Accepted,
A-Accepted.

**^(2)^**The DMS-10 listing includes the one and two bay version and its
application as an HSO, SSO or LCC.

**^(3)^**The DMS-100 listing includes its application as a DMS-200
tandem office and the smaller version of the SuperNode configuration,
the DMS‑SuperNode SE.

**^(4)^**DCO listing includes the DCO-SE one and two bay configurations
and DCO RNS.

**^(5)^**The listed software/firmware system release is the most recent
system release that was reviewed by RUS and found to be fully compliant
with all requirements of 7 CFR 1755.522, RUS General Specification for
Digital, Stored Program Controlled Central Office Equipment (Form 522).
Other system releases may also be acceptable. For information on
specific releases, please contact the Chairman, Technical Standards
Committee \"A\" (Telecommunications), Rural Utilities Service,
Stop 1598, 1400 Independence Avenue, SW., Washington, D.C. 20250-1598.

**^(6)^**The 5ESS‑2000 digital exchange listing includes the compact
digital exchange 5ESS‑2000 (CDX) and the very compact digital exchange
5ESS‑2000 (VCDX) in host and remote switching terminal configurations
(DRM). The listing also includes the EAIU/BZ-RS Unit, also called the
5E-XC Remote Line Unit. When a VCDX is upgraded to a CDX or full sized
5ESS-2000, it can host the listed RSTs. Unless it is upgraded it can
only host the EAIU. Emergency call processing using the BZ-RS is only
offered for EAIU Units that are hosted from a full sized 5ESS-2000 or
from a DRM. The BZ-RS cannot be used to provide emergency call
processing on EAIU Units hosted from a CDX or from a VCDX. System
Release 5E16.2 is designated 5E-XC Service Rich Software by Lucent.

**^(7)^**The MDX-I listing is for a minimum system configuration of four
shelves, each containing no more than 100 lines or 25 percent of the
total equipped lines, whichever is less.

**^(8)^**The EWSD listing includes the EWSD Small Exchange (EWSD-SX) and
the Line Trunk Group‑O (LTGO).

**^(9)^**Systems used for line access for this switch must be included
in the RUS *List of Materials Acceptable for Use on Telecommunications
Systems of RUS Borrowers* in category ae -- Access Equipment.

**^(11)^**Consists of the Taqua T7000 Class 5 Packet Switch and VoIP
Software application

**^(12)^**This system includes PSX, SGX and EMS deployed on Sun Netra
servers.
