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 Supports upstream modes transparent transmission and convergence
l Built-in TDM switched network ensures quality of private line data

l Inherits original private line services using original private line networks
l Terminals and user experience remain the same

Enterprise TDM Private Line Access Services IP/MPLS Network

G.SHDSL or E1 access

l Upstream through MPLS PWE3 by working together with SPUB
l Both G.SHDSL and E1 ports support PW upstream

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)
