Meaning 
The destination is a voice device and thus incompatible. 
Further addressing information is required to complete the call. The user 
is returned to the DTRX * prompt. 
The destination device’s data rate is not compatible with that of the 
source device. (Speed conversion is allowed if XON/XOFF Flow Control 
is enabled). The user is returned to the DTRX * prompt. 
Access to the destination device is not allowed. This can be due to ten- 
anting, because the data station is programmed as Receive Only, or 
because the destination is not accessible by the caller. The user is re- 
turned to the DTRX * prompt. 
The destination is busy and queuing is enabled. The “Queue Position” 
message follows if the destination is a dataset. The DTRX is dropped 
until it is needed to display the call progress messages, or the next queue 
position. When the destination device becomes free, the “Ringing” and 
“Connected” messages follow. 
This message occurs after every system clock minute. It indicates the 
user’s new queue position, if changed. If the position has not changed, 
“.” is appended to the displayed position number. (e.g. Queue Position 
02.) The DTRX is obtained for this write operation and is dropped after 
it is completed. 
There is no room in the queue. The user is returned to the DTRX * prompt. 
The entered account code is programmed as inactive (Verified Account 
Code), is invalid or is not the length specified in CDE Form 04 (System 
Options/System Timers). 
For ACD only, when “MONITOR ACD” is selected. This message is dis- 
played if the user enters MQNITOR ACD in an ACD software load and 
System Option 104 (Automatic Call Distribution) is disabled. 
The system has changed the data rate of the dataset to be compatible 
with the destination. The user must change the terminal’s data rate as 
indicated. The DTRX is dropped at this point. 
If DTRX Herald is not enabled, only the “*‘I (asterisk) prompt appears. 
DTRX dropped due to timeout or user request (“BYE” command or 
 at DTRX * prompt). 
There are no DTRX links currently available. 
The system has disconnected the call. This could be due to a link failure. 
Check the DATA SMDR reports for more information. 
The user disconnected the call using the Disconnect key.

Data: Modem Pooling 
Description Modem Pooling is a data application feature using voice communication 
lines. Modem pooling permits communication between modems and 
DATASET 2100 Series datasets. Each pooled modem consists of a modem 
and a dataset. The dataset connects to a Digital Line Circuit, and 
communicates with datasets within the PABX. The pooled modem connects 
to an ONS or OPS Line Circuit, which communicates directly with internal 
modems, or with external modems via trunks. 
A collection of pooled modems organized into a hunt group is called a 
modem pool hunt group. 
A dataset user can access a modem pool hunt group to obtain a pooled 
modem for data transmission to a modem user over the public network. If 
the modem pool hunt group or the trunk greup is busy, the user can queue 
for it; see Modem Pooling Queuing. 
A modem user, internal or external, can access a modem pool hunt group 
to obtain a pooled modem for communication with a dataset within the 
PABX. If the modem pool hunt group or the destination dataset is busy, the 
user can queue for it; see Modem Pooling Queuing. 
Modem Pooling calls may also be made by using system abbreviated dial 
numbers. 
Conditions The following conditions apply to this feature: 
l COS Option 217 (Direct to ARS) is ignored for outgoing data calls. 
2-136 Issue 1 Revision 0 March 1997  
						

							Features 
l If the originator does not dial a specific modem pool hunt group access 
code, a pooled modem is selected from the default modem pool hunt 
group, if programmed. 
l On incoming or internal calls, the system prints TRUNK SMDR reports 
for the trunk and Data SMDR reports for the pooled modem if they are 
enabled in the respective COS. The reports can be correlated by the 
originating device’s identity and the time the call was started. COS 
Option 806 (SMDR - Record Incoming Calls) must be enabled to 
generate SMDR records for incoming calls. COS Option 906 (Data 
SMDR - Does Not Apply) must be disabled for pooled modems to 
generate SMDR records for incoming calls. 
l On external ADL or DTRX-originated calls, the system generates a 
TRUNK SMDR report for the pooled modem and a Data SMDR report 
for the originating data station. 
l Only DATASET 2102 and 2103 datasets can be used as modem pool 
devices. 
l All pooled modems in the Modem Pool Hunt Group must have the same 
Operating Mode (all Originate or all Answer or all Both). 
l The pooled modems in the default modem pool hunt group can only be 
programmed for Both (Answer and Originate) mode. 
l A dictation trunk cannot be used for an outgoing modem pool. 
Programming Programming varies depending upon the modem configuration as 
described below. 
Internal/Incoming Modem Users 
Modem users can be a trunk, station (ONYOPS), SUPERSETtelephone 
(with acoustically-coupled modem), or a console (can only transfer a 
modem). 
To pernit a modem user to make calls to datasets, enable COS Option 704 
(Incoming/Internal Modem Pooling Access) in its COS. This is required 
because the system normally bars calls between voice and data devices. 
Modems of pooled modems within the modem pool hunt group should be 
in auto-answer mode. 
If desired, enable Option 900 (Data Station Queuing) in the modem user’s 
COS; see Modem Pooling Queuing. 
Pooled Modem 
Pooled modems are programmed in CDE Form 36 (Modem Assignment); 
for each pooled modem, assign: 
l Bay/Slot/Circuit location of its ONS (or OPS) Line (system-supplied), 
l Data Circuit Descriptor Number (CDN) that applies to its dataset, 
l Bay/Slot/Circuit location of its dataset’s Digital Line, 
. 
extension number, 
. tenant (default is l), 
l DTE Profile Number (optional), 
March 1997

							Features Description 
Operation 
l Class of Service (COS) (default is 1) and Class of Restriction (COR) 
(default is I), 
l mode: Answer, Originate, or Both (default is Both), 
l auto-dial capability: Auto dial or Non Auto dial (default is Non Auto dial). 
Modem Pool Hunt Group 
Program the extension numbers of the required pooled modems to a 
Hunt Group in CDE Form 17 (Hunt Groups). 
Assign an access code to the modem pool hunt group. 
If desired, make this the default modem pool hunt group. Users do not 
need to dial the modem pool access code. Only one default modem 
pool hunt group can be programmed in the system. 
Only pooled modems of the same operating mode can be assigned to 
the same modem pool hunt group. 
Assign a hunt group name to allow access via the DTRX Call by Name 
feature. 
To provide immediate DTRX access for incoming or internal modem 
pooling callers, enable DTRX for the modem pool hunt group in the 
Options subform of CDE Form 17 (Hunt Groups). If DTRX is disabled, 
DTRX callers must wait for the interdigit time-out (up to 15 seconds) 
before receiving a response. The DTRX option does not affect outgoing 
modem pooling calls. The DTRX option can only be enabled if DTE is 
programmed in the pooled modem and the mode of the hunt group is 
Answer or Both. 
Internal Modem User (Station, SUPERSETTelephone, or Console) 
l Dial: 
- Data Station or Data Hunt Group access code (where default mo- 
dem pool hunt group is selected, if programmed) 
or, 
- Modem Pool Hunt Group access code for DTRX access 
or, 
- Modem Pool Hunt Group access code plus Data Station or Data 
Hunt Group access code. 
l When answer tone is heard, the modem pooling call is established. Put 
the modem on line. 
Incoming DISA Trunk Modem Call 
l From the Public Network, using a DTMF telephone, dial the DISA 
telephone number. The PABX answers and returns dial tone. 
l Dial the DISA Access Code (normal DISA trunk) or Account Code (if a 
Special DISA trunk). Once access is allowed, the system returns dial 
tone.
