MXK
The MXK-ADSL2+-POTS-BCM-48A-2S is a two-slot card and
provides 48 ports of integrated ADSL and POTS VoIP service. This
card supports the ANSI T1.413 Issue 2, G.992.1 (G.dmt) and G.992.2
(G.lite), G.992.3 and G.992.4 (ADLS2), G.992.5 (ADSL2+), Annex A,
and Annex M ADSL standards. Also supports SIP, SIP-PLAR, H.248,
and MGCP protocols.
The MXK-ADSL2+-BCM-48A, is a single slot card that supports
ADSL2+ Annex A/M. The standards supported are ANSI T1.413
Issue 2, G.992.1 (G.dmt), G.992.2 (G.lite), and ADSL2+ (G.992.5)
standards.
The MXK-ADSL2+-SPLTR600-BCM-48-2S, and
MXK-ADSL2+-SPLTR900-BCM-48-2S are two-slot cards with an
integrated POTS splitter to provide 48 ports of integrated ADSL and
POTS service. Each of these lines are combined with the ADSL2+
signal internally and exits the line card in the subscriber direction
with both ADSL and POTS on the loop. In the network direction the
POTS is split from the ADSL signal keeping POTS on copper pairs
and placing the ADSL data information on the IP network.
The MXK-ADSL2+-SPLTR600-BCM-48-2S, and
MXK-ADSL2+-SPLTR900-BCM-48-2S cards support the ANSI
T1.413 Issue 2, G.992.1 (G.dmt) and G.992.2 (G.lite), G.992.3 and
G.992.4 (ADSL2), G.992.5 (ADSL2+), Annex A standards and
Annex M ADSL standards.
All ADSL cards support VoIP POTS services.

MXK-EFM-SHDSL-24-NTP
MXK-EFM-SHDSL-24-NTWC
The MXK-EFM-SHDSL-24 NTP card provides network timing
reference and line power. The timing reference enables the card to use
the MXK timing as the SHDSL line clocking. This allows an SHDSL
CPE to derive timing from the input of the SHDSL lines. It then can
use that timing/clocking to provide timing to other subtended
devices.The line power feature can be used to power CPEs such as the
SkyZhone to eliminate the need for local power. The power is
combined with the data and sent out over the 24 SHDSL ports to
downstream CPE devices such as the SkyZhone. One
MXK-EFM-SHDSL-24-NTP line card can provide power and data
for up to 12 CPE devices.
The MXK-EFM-SHDSL-24 NTWC card provides network timing
reference and wetting current. The network timing reference allows
SHDSL lines to use the backplane clock to clock T1/E1 traffic
eliminating the need for a clock source at each location where remote
devices are installed.
