Using a Web browser to complete Model 3095 configuration 39
Model 3095 mDSL DACS Getting Started Guide 3 • Configuring the DACS for operation
3095 configuration are stored in volatile DRAM first, enabling the user to set the box up with a working
configuration before committing it to storage in FLASH. The configuration changes become permanent
when you select Record Current Configuration.
Note If you want to save the configuration changes that you have made,
you must click on
Record Current Configuration, otherwise all con-
figuration changes will be lost if the power to the Model 3095 is
turned off.
• Hard Reset—this button (see figure 20) causes the Model 3095 to perform a cold restart. When you select
Hard Reset, the DACS confirms that you want to execute this command. Then, the DACS will disconnect
all current sessions, re-initialize the interfaces, and re-load configuration parameters from FLASH.
• Set Factory Default Configuration—this button (see figure 20) clears out the configuration in FLASH and
loads the factory default parameters into FLASH memory. The factory default settings will not execute on
the Model 3095 until it is re-booted by doing a Hard Reset.
Note Set Factory Default Configuration (figure 20) will delete any routing
information, the Model 3095’s Ethernet IP address, and any other
site-specific settings made for your particular installation. You will
have to re-enter the Model 3095’s Ethernet IP address and netmask
using the rear panel control port before using the HTTP/HTML
Management pages.
Configuring the DS0 mapping
You need to make internal connections between an mDSL modem link and its destination. The destination of
an mDSL modem may be at the end of a T1 or E1 link, or another mDSL port. Each mDSL modem inside
the 3095 DACS 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 mDSL modem. The most common destination for the
mDSL modems will be at the remote end of a T1/E1 WAN link.
Note 1. The maximum DTE data rate between an mDSL modem and
another mDSL modem or an E1 Wan link is 2.048 Mbps. If the con-
nection is mapped between two mDSL modems, you may map all 32
DS0 channels between them. If the connection is mapped between
an mDSL modem and an E1 Wan link, the data rate may be set at
1.984 Mbps, but only 31 DS0 channels may be mapped since time
slot 0 of the E1 link is used for synchronization, CRC (if selected),
alarms, etc. because the 3095 E1 ports terminate an E1 line.
2. If you are connecting to T1 WAN links, you may connect an
mDSL modem at a DTE data rate of 2.048 Mbps through two T1
links by mapping 24 DS0 channels to one T1 and the remaining 8
DS0 channels to a second T1 line.
The DS0 Mapping window (Digital Cross Connect Configuration) provides full grooming. The three groom-
ing variations define that connections may be between (1) an mDSL modem and a WAN port, (2) between
