E1 mapping in SHDSL:
• ITU G.991.2 Appendix E.5 (= ETSI TS 101 524 D2048U) Clear channel TPS-TC
framing for unstructured E1 (plesiochronous SHDSL transport).
• Interface SHDSL rate of 2056 kbit/s.
Flexible TU-12 slot / SHDSL port mapping assignment.
SHDSL span fault management Incoming & Outgoing loopbacks at SHDSL interface
for installation or fault localization-
Surge protection K.20 and K.21.
SDH Element Management (Alcatel-Lucent OMS, ITM-CIT):
• Remote NTUs management via in-band SHDSL EOC channel (~3.3kbit/s). All
provisioning of NTU device made via it’s associated LTU.
• Support of standard EOC protocol + extensions
• Managed Remote SHDSL Power Supply (RPS) module support
• Enhanced PM support
Mapping
• The 1643 AM / 1643 AMS support an AU-4 <-> VC-4 <-> TUG-3 <-> TUG-2 <->
TU-12 <->VC-12 <->E1 mapping scheme for each VC-12 created and terminated
in the system
• The 1643 AM / 1643 AMS support an AU-4 <-> VC-4 <-> TUG-3 <-> TUG-2 <->
TU-12 <-> VC-11 <->DS1 mapping scheme for each VC-11 created and terminated
in the system
• The 1643 AM / 1643 AMS support an AU-4 <-> VC-4 <-> TUG-3 <-> TU-3 <->
VC-3 <->E3 mapping scheme for each VC-3 created and terminated in the system
• The1643 AM / 1643 AMS support an AU-4 <-> VC-4 <-> TUG-3 <-> TU-3 <->
VC-3 <-> DS3 mapping scheme for each VC-3 created and terminated in the
system.
Connectivity
• The equipment supports VC-4 connectivity
• The equipment supports bi-directional, non-blocking cross-connection switching at
the VC-3 level and at the VC-12 level within one selected VC-4 from each line
interface.
Protection schemes
• The equipment provides 1 + 1 MSP protection for STM-1 optical aggregate or
STM-1 optical or electrical tributary interfaces
• The equipment provides VC-11/VC-12, VC-3 or VC-4 SNC/N (1643 AM for
STM-4 version only) protection.
