Configuring the DS0 mapping
You need to make internal connections between an G.SHDSL modem link and its destination. The destina-
tion of an G.SHDSL modem may be at the end of a T1 or E1 link, or another G.SHDSL port. Each
G.SHDSL modem inside the 3096RC T-DAC is configured by selecting the number of DS0 time slots, each
time slot being 64 kbps. You may choose to map from 1 to 31 DS0 time slots in the G.SHDSL modem. The
most common destination for the G.SHDSL modems will be at the remote end of a T1/E1 WAN link.
The G.SHDSL ports connect at speeds up to 4.6 Mbps (72 DS0s). A maximum of 31 DS0s can be mapped to
an E1 port, while a maximum of 24 DS0s can be mapped to a T1 port. When configuring DS0 maps, the fol-
lowing conditions may be encountered:
•
Several DSL ports running at low speeds (128 kbps, 256 kbps, etc.) for uplink on a single E1 or T1 line. In
this case, create a DS0 map from each port to the selected T1/E1 port. Make sure assigned DS0s in the
T1/E1 port are unique for each DSL port.
•
DSL ports running at T1 or E1 speeds. In this case DS0s are mapped on a one to one correspondence to
T1/E1 uplink ports.
•
DSL port speed beyond T1/E1 link speed. Split and map DS0s onto two or more T1/E1 ports.
The DS0 Mapping window (Digital Cross Connect Configuration) provides full DS0 grooming and supports
three variations. You may define connections between (1) a G.SHDSL modem and a WAN port, (2) two
G.SHDSL modems, or (3) two WAN time slots. When no mapping is defined, the G.SHDSL modems (nor
the WAN ports) have no destination. The T-DAC functions as a 2-dimensional matrix switch.
To define the DS0 Mapping for the G.SHDSL modems, do the following:
1. On the Configuration Menu click DS0 Mapping hyperlink.
2. In the DACS Display Type drop-down menu (
figure 28
), select displayLongForm(0).
