There are 2 version of the 8DBRA card, one with 2 RJ45s and 2 HD44 connectors that require 2 fanout cables, each with one DE9 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 DCE (8DBRA)
5 Transmitted Data DTE
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/E1/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 the 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.
Below are the screens showing the “M Mode Setup” selection, the 56/64K selection.→

Card reset celars all 8DBRA card mapping (8DBRA ports and time slots to Virtual Ports). The reset process takes a bit less than one minute.

First, note that the chassis has 8DBRA cards in slots 3 and 4.

G -> Upgrade Firmware
Select “B - > Backup Setup” Select “1+1 Port Backup”. This selection pairs ports 1 & 5, 2 & 6, 3 & 7, 4 & 8. They are digitally bridged together.
SLOT 3 8DBRA P1 === Backup Setup === 12:01:19 12/01/2010 ARROW KEYS: CURSOR MOVE, TAB: ROLL OPTIONS
Backup Type : 1+1 Port Backup
Warning!! Change Backup Type will clear map.
Next you can select “S - > RS232 Config Setup”. This is reference only. The card supports any async speed up to 19200 bps regardless of what is on this screen.
SLOT 3 8DBRA P1 === RS232 Setup === 12:04:25 12/01/2010 ARROW KEYS: CURSOR MOVE, TAB: ROLL OPTIONS
RATE : 9.6KBps
Interface : 8RJ
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 “Enter” key to accept the selection. Using the arrow key does not accept the mapping.

Note: i=idle, 1~8=RS232 port number
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.
8DBRA Quad T1 ================ PO/TS D SL/PO TS 1 1 d 1 1 1 1 2 d 1 2 1 1 3 d 1 3 1
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.
