SHDSL Service

SHDSL technology provides high-speed symmetric data service
on a single pair or two pairs of twisted pairs. SHDSL technology
can transport data symmetrically at data rates from 192 Kbps to
2,320 Kbps or 2.3 Mbps. SHDSL utilizes a single copper wire pair,
making it an affordable DSL option attractive to small businesses.
ZXMSG 5200 also provides SDL card to support the SHDSL
(based on ATM). Each SDL card provides 16 SHDSL ports.
