Table 2. H802EDTB provides these benefits:
|
Application |
Access Mode |
Upstream Mode |
Benefit |
|
Enterprise TDM Private Line Access Services — SDH/DDN Network |
G.SHDSL access Enterprise PBX and V.35 routes access G.SHDSL CPEs through E1 lines |
l Upstream through the intra-board E1 port |
l Inherits original private line services using original private line networks |
|
Enterprise TDM Private Line Access Services — IP/MPLS Network |
G.SHDSL or E1 access |
l Upstream through MPLS PWE3 by working together with SPUB |
Traditional private line services are completely migrated to IP/MPLS networks after entire network IP restructuring or IP restructuring for only access and convergence networks but not for DDN core networks |
|
Enterprise PBX Access Services — NGN/IMS Network |
G.SHDSL (supporting PBX in a long distance) or E1 access |
Upstream through VoIP with the support of H.248+IUA or SIP |
Inherits original ISDN services |
H802EDTB provides these external interfaces:
· 16-channel SHDSL port:
- G.991.2 Annex A and Annex F (Standards applicable for North America)
- G.991.2 Annex B and Annex G (Standards applicable for European)
· 16-channel E1 port:
- G.703 (Physical/electrical characteristics of hierarchical digital interfaces)
- G.704 (Synchronous frame structures used at 1544, 6312, 2048, 8448 and 44 736 kbit/s hierarchical levels)
- G.706 (Frame alignment and cyclic redundancy check (CRC) procedures relating to basic frame structures defined in recommendation G.704)
- G.961 (Digital transmission system on metallic local lines for ISDN basic rate access)
