8 DBRA (Data Bridge Card) Startup and Configuration Guide
Ver 2, April, 2011
There are 2 version of the 8DBRA card, one with 2 RJ45s and 2 HD44 connectors that require 2
fanout cables, each with one D 9 and 2 DB25s. The other card has 8 RJ45 connectors. The all
RJ45 version is preferred because the connectors are all the same. The card supports transmit
data, receive data and ground on each port. RS232 control leads are not supported.
The 8DBRA card with the 8 RJ45 connectors provides easier, cleaner looking connections.
Pin outs for the RJ45 connectors:
Pin Number Signal Source
1 Signal Ground Common
3 Received Data DC (8DBRA)
5 Transmitted Data DT
7 Signal Ground Common
The 8 DBRA card supports asynchronous ports at any speed up to 19,200 bps. The speed
setting in the 8DBRA card setup screen is for reference only.
The 8DBRA card is compatible with other 8DBRA cards and any synchronous RS232 56Kbps or
64 Kbps card or 56K or 64K OCUDP from Loop or other manufacturers (tested!). The 8DBRA
card uses oversampling. See Page 16 for a description of the oversampling technique. Terminal
devices attached to non-8DBRA cards must run at the same speed as the devices attached to
the 8DBRA cards.
The 8 ports of the 8DBRA can be mapped into 3 or 4 Virtual Ports (VP). If the 8DBRA card is
configured for “NO Backup” or “1+1 Port Backup”, all 4 of the Virtual Ports are available.
Backing up the entire card in the same or a different chassis limits the card to 3 virtual ports.
Data is carried to the backup card, whether in the same chassis or to a remote site, via one of
the Virtual Ports (VP4).

The 8 DBRA card has 32 time slots for each Virtual Port, for a total of 128 time slots. Any one of
the RS232 ports can be mapped to maximum of 20 downstream endpoints (DS-0s) on a
multidrop circuit.
Mapping is a 2 step process. The first step is to map the physical RS232 ports to virtual ports,
then map the virtual ports to one or more DS-0s. The card mapping is a sub menu for the card
slot. The Virtual Port mapping is done at the AM3440 system time slot interchange (TSI)
mapping level.
The 8 DBRA card protection mode allows port/card protection on the same card, on a different
card in the same chassis, or on a different (remote) chassis.
The 8DBRA card can be used at a central host site, a midpoint remote drop location, or endpoint
remote drop location.
At a host site, backup may be:
–To the backup ports (ports are paired 1 and 5, 2 and 6, 3 and 7, 4 and 8).
–To a second card in the same chassis. Card slots are paired 1&2, 3&4, 5&6, etc.
–To a second card in a different chassis at another location
At a remote drop site (downstream location), backup may be:
–To the backup ports (ports are paired 1 and 5, 2 and 6, 3 and 7, 4 and 8).
–To a second backup card in the same chassis
All 8 ports of the 8DBRA card can be mapped to different locations unless the card is set for 1+1
port backup. In 1+1 port backup, 1&5, 2&6, 3&7, 4&8 are paired, limiting the ports to 4 pairs.
The 8DBRA card can be used as a host end digital bridge device or an 8 port asynchronous data
card. The 8DBRA card is most useful, and is unique for its function as a host digital bridge
device, where data from a host computer attached to one of the RS232 host ports is broadcast
out to as many as 20 endpoints. At the card level, RS232 ports are mapped to Virtual Ports
(VPs). At the Time Slot Interchange (TSI) map level, the Virtual Port (VP) time slots are mapped
to DS-0s on T1/ 1/FOM circuits. Therefor mapping is a 2 step process.
If a card is used as an 8 port asynchronous port card only (not for its bridging capability), each
port is mapped to a different time slot on a Virtual Port. As an 8 port asynchronous card in a
point to point application, only 8 of the 128 time slots are used. Only one Virtual Port (VP) needs
to be used.

Step One, setting up t e card mode for 56 Kbps or 64 Kbps operation:
The 8DBRA card can be set to over sample at either 56 Kbps or 64 Kbps. All 8 ports share the
same sampling rate of either 56 Kbps or 64 Kbps. After the card is changed from one rate to the
other, it is necessary to reset the card.
When the 8DBRA card is reset, all card mapping is set to default (no mapping). The card reset
takes about 50 seconds to complete. Be patient.

Back out to the Port Menu and select “K - > Port Map Setup” See the port map setup on the
next page. You will need to map only ports 1, 2, 3 and 4.
In the example below, RS232 (the physical port) is mapped to time slots 1, 2 and 3 of Virtual Port
1. This will allow the data from RS232 port 1 to be mapped to 3 different DS-0s. Use the arrow
keys to move down the screen from Virtual Port, to TS start, to Total TS, RS232 Port and
Command. When you get down to “Command : Set”, use the “ nter” key to accept the
selection. Using the arrow key does not accept the mapping.

After the RS232 ports are mapped to the Virtual Ports, back out to the Main Controller Menu,
then select “S - > System Setup” and “C - > TSI Map Setup”. Map the Virtual Ports to the
appropriate DS-0s.
In the example below, Virtual Port 1 of the 8DBRA in slot 3 is mapped to DS-0 number 1 on 3
different T1 circuits on the Slot 1 Quad T1 card. PO is the port, TS the time slot, SL is the slot
number. Immediately below is a snapshot of the key data from the TSI mapping page.

When mapping the System Time Slot Interchange (TSI), you are always mapping 8DBRA virtual
ports. The first column above labeled “PO” under 8DBRA is the Virtual Port number. RS232
ports were previously mapped to the virtual ports using the card slot sub menu. See the top of
this page.

Since 1+1 Port Backup was selected, host ports 1 & 5, 2 & 6, 3& 7, 4 & 8 are bridged. Host data
transmitted into either port and is received downstream via the Virtual Port time slots mapped to
the T1 DS-0s. Remote terminal responses are received on both of the paired ports.
In summary, follow these steps:
1. Select the backup type.
2. Map RS232 ports to the Virtual Ports through the card slot sub menu.
3. Map the Virtual Ports to the T1/ 1/FOM time slots on the System Setup TSI Map Setup.

Mid point 8DBRA wit local RTU and data passed downstream:
The host is presumed to be mapped per the first example on pages 2 through 6. The midpoint
AM3440 will have an 8DBRA card and a Quad T1 card. We want to do the following:
Set the 8DBRA card for 1+1 Port Backup
On the 8DBRA Port Map Setup, map RS232 port 1 to the upstream host T1 to the AM3440.
On the 8DBRA Port Map Setup, map RS232 port 2 to the downstream T1 to the V4200

Data from the host comes out RS232 Ports 1 and 5 because of the 1+1 Port Backup. RS232
Port 1 can be connected to a local RTU. To get data downstream, connect RS232 Port 5 to
RS232 Port 2 or 6 with a 3-wire RJ45 to RJ45 crossover cable. See the table on page 1 for
pinouts. Connect the ground 1 to 1 or 7 to 7. Connect 3 to 5 and 5 to 3 to cross the data leads.
