3 SYNCHRONIZATION/EXTERNAL TIMING INTERFACE
STANDARDS
Please read the text of section 3 completely before proceeding
with this section of the questionnaire. If you have any questions
about the requirements of this section and its applicability to your
DUC, or have suggestions for improving the format of this
section, please contact the AT&T Common Systems
synchronization SME. Text of explanations to questions posed in
the questionnaire should be posted in the Notes section.
3.1.1 s the DUC designed to conform to Telcordia GR-1244-
CORE and GR-499-CORE standards for
interconnection to a GR-378-CORE compliant Timing
Signal Generator system? Enter Yes or No. If
response is No, skip to 3.2.1. If response is Yes,
proceed to 3.1.2. yes n/a
3.1.2 Will the DUC, as it will be deployed in the AT&T
network, require an external frequency timing reference
sourced from the site BITS systems? Enter Yes or No.
If response is No, explain why the DUC does not require
an external frequency timing reference sourced from the
site BITS systems (e.g.: asynchronous only applications
such as metro Ethernet, asynchronous IP transport,
DUC will be line or loop timed, etc). yes n/a
3.1.3 If 3.1.2 is No, mark 3.1.3 N/A. If 3.1.2 is Yes, does the
DUC accept GR-1244-CORE compliant DS1 or CC
frequency timing input references? Respond Yes or
No. If 3.1.3 is Yes, explain the number and type of
input references in the notes. If 3.1.2 is NO, explain the
signal format of the external frequency references that
are supported by the DUC. yes n/a
3.1.4 Describe the external timing input interface in the notes.
Include a description of the type of connections, the
location of the connections, and the termination
impedances supported for each signal format. If the
external timing input interface is not compliant to AT&T
standards as described in section 3.0, please explain
how the non-compliant interface will be mitigated. yes n/a
3.2.1 Will the DUC, as deployed in AT&T, require a separate
dedicated GPS antenna and receiver system to supply
precision frequency, time, phase, or location
synchronization? Enter Yes or No. If the response is yes n/a
