This modem is suitable for connection to BT circuits  
with signalling at a nominal frequency of 2280 Hz and  
may be connected to multipoint or point-to-point circuits.  
The apparatus does not require signalling or otherwise use  
the frequency range 0200 Hz.  
CAUTION  
Users should not attempt to  
make such connections  
themselves, but should  
contact the appropriate  
electric inspection authority,  
or electrician, as appropriate.  
No d.c. interaction is intended between the modem and  
the telephone network.  
This apparatus may be directly connected to a  
speechband circuit or connected to a relevant branch  
system for speechband circuits.  
The Load Number for this equipment is on the label on  
the modem. The Load Number (LN) assigned to each  
terminal device denotes the percentage of the total load to  
be connected to a telephone loop which is used by the  
device to prevent overloading. The termination on a loop  
may consist of any combination of devices subject only to  
the requirement that the total of the Load Numbers of all  
devices does not exceed 100.

The COMSPHERE 3000 Series Carrier has 17 slots  
which can hold up to 16 modems and one SDU. The SDU  
is required when the modems in the carrier are controlled  
by an NMS, or when multiple carriers in a cabinet  
configuration are to be controlled by a single SDCP. The  
SDCP of the COMSPHERE 3000 Series Carrier is the  
user interface to the 3811Plus modem. A single SDCP can  
control modems in up to eight carriers.  
To install a 3811Plus modem into the carrier, perform  
the following steps.  
" Procedure  
1. At the rear of the carrier, install the rear connector  
plate. Make sure the plate uses the same slot  
position as that intended for the modem.

2. At the front of the carrier, hold the modem  
vertically, with the latch on its faceplate in the  
open position, and insert it into the top and bottom  
card guides of one of the slots numbered 1–16.

Slide the modem into the slot, aligning the modem  
with the rear connector plate, until the backplane  
connector and DTE connector seat firmly into the

The 3811Plus modem has several factory preset  
templates that contain the proper configuration options  
(straps) for different environments. Modems are shipped  
from the factory with the Async Dial default configuration  
options stored in memory. To prepare the modem for Sync  
Dial, Sync Leased, UNIX Dial, Cellular (Mobile), or  
Cellular (PSTN), you must change the factory setting,
