NOTE:The number of x’s in the above strings is equal to the value 
of smdi_stop, while the number of r
’s, e
’s, b
’s, and s
’s is 
equal to the value of smdi_start. To modify the above for 
another digit plan, use the appropriate number of r’s, b’s, 
s’s, e’s, and x’s. In the example, 10 is used (causing 
Amanda to timeout after 1 second if the packet has not been 
received) because it works for all serial integration. The 
number is in tenths of seconds.
To program the message waiting lights for NEC 2000, use the following in 
the Method field of the two notification records used for Light ON and Light 
OFF:
\B represents Ctrl+B, the start of transmission (STX) character. %E should 
be the same number of digits and smdi_start specifies.
N
OTE:These examples uses logical serial port 3; for other ports, the 
3’s would have to be replaced.
Generic
This section covers a generic serial integration. It is designed for any 
telephone switching system using serial integration other than those that:
 Use Bellcore Standard SMDI
 Are NEC 2000 or NEC 2400 systems
 Are AT&T System 75 or Definity-G3 systems
integration 1094rrrxx
integration 1095bbbxx
Light ON:@S(3,’\B06%E01\N’)
Light OFF:@S(3,’\B07%E01\N’)

To set configuration options for generic serial integration:
1. Follow steps 1 through 11 in the Bellcore Standard SDMI procedure “To 
modify configuration options for use with Bellcore Standard SMDI,” in 
the “Bellcore Standard SDMI” section.
2. Change the smdi_type option to:
To :
smdi_type generic
3. Modify smdi_base_port 1 if the first port on the telephone switch-
ing system is not identified as the logical port 1. For example, some tele-
phone switching systems use the port’s extension or another logical 
terminal number to identify the port. The first port may be extension 
241, with the second port 242, etc. These numbers must be consecu-
tive. For example, if the first or base port is 241, you use 
smdi_base_port 241.
4. You can also set smdi_pretimeout
 n, where n is the maximum 
number of seconds that an SMDI packet can precede the forwarded call. 
The default is 50.
5. You must set smdi_start
 n, where n is the position in the integra-
tion packet sent by the telephone switching system where the field con-
taining the port number starts. Start counting positions in the packet with 
the number 1. The default is 8.
6. You must set smdi_stop
 n, where n is the position in the integration 
packet sent by the telephone switching system where the field contain-
ing the port number ends. Start counting positions in the packet with the 
number 1. The default is 11.
7. You must set smdi_max
 n, where n is the maximum number of char-
acters expected/accepted per packet. The default is 143.
8. You must set smdi_term
 n, where n is the termination character set 
(if there is one). Leave this option empty if the packets are terminated 
only by receiving smdi_max characters. 
						

							Chapter 12: Using Serial Integration 151
9. You can also set smdi_delay
 n, where n is the number of tenths of 
seconds that Amanda waits after the call is answered before looking for 
integration information. This allows more than one packet to be sent to a 
port per telephone call. Amanda uses the last (most recent) packet. The 
default is 0. The range is 0 to 255.
You must also modify the system integration patterns (stored in 
C:\AMANDA\PBX.DB\1001.PBX) using the Amanda Setup utility 
(selection 3) or the JOVE utility. You may need to write appropriate 
notification records to turn message lights on and off. Consult your PBX 
manual for this information.

Configuring Types of Lines
Most people connect Amanda to standard analog lines known as loop start 
lines that indicate a new call by sending an AC voltage to the telephone 
ringer. 
You can also connect Amanda to Direct Inward Dialing (DID) lines with an 
appropriate DID interface unit. Amanda assumes that you have a DID 
interface unit, such as Exacom DID-200 Series, that processes a hookflash as 
battery reversal.
When you use DID, Amanda receives the last few digits of the dialed 
number. Those digits are used as (or modified by programming to be) the 
internal extension. Then the caller does not have to enter an extension.
Use the following Telephone Line Options Diagram to determine what 
configuration settings you need.
C
AUTION:The configuration option ring_mode is a global set-
ting. If any lines into Amanda are loopstart (such as 
those that perform notification records), ring_mode 
must be true.

Sharing Amanda
Sometimes more than one company or department share an Amanda system. 
Specific ports are assigned to specific groups. For example, on a two-port 
system shared by two companies, one company receives calls on port 1 and 
another on port 2. This affects the configuration options that determine 
which mailbox is used for: 
						

							156 Installing [email protected]/DOS
 The company or initial greeting that callers hear when they call one 
of the companies.
 The caller instructions greeting for each company.
The mailbox/extension for each company when 0 is dialed for the opera-
tor needs to be included in the menu for this mailbox.
 The employee directory that contains the names of all the users as 
they appear in the Directory Name 1 and Directory Name 2 fields.
 The direct message mailbox that allows you to record a message for 
a mailbox without having to transfer to that extension. You hear ei-
ther the mailbox’s greeting or the name and extension recording (de-
pending on the setting for the short_direct_send configuration 
option). For example, you can leave a message for someone that you 
know is out of the office or not to be disturbed. 
When multiple companies share an Amanda system, they divide the ports 
between them by doing either of the following:
 Dedicating each port to a specific company greeting using the 
box_grt configuration option. 
 Identifying the incoming CO lines with the Amanda mailbox that has 
the same ID number. (To use this method, the telephone switching 
system must send some sort of CO line ID number.)
This tenant services feature is based on dynamic port allocation, which 
means that any Amanda port can receive the calls for any company shar-
ing the Amanda system. This eliminates the need for dedicating ports to 
each company.
Using the box_grt Configuration Option
Typically, you dedicate each port to a specific company greeting using the 
box_grt configuration option.
To use the box_grt:
 In the Per Port section of Advanced Configuration, change the mail-
box for the company greeting on a per port basis. 
Suppose the first company uses ports 1 and 2, and the second company 
uses ports 3 and 4. Then box_grt for ports 1 and 2 might be set to mail-
box 990, while box_grt for ports 3 and 4 might be set to mailbox 880. 
						

							Chapter 13: Miscellaneous 157
Using Incoming Trunk Call and CO Line IDs
Most telephone switching systems use three or four digit numbers to identify 
a trunk call or CO line. You can use these IDs for dynamic port allocation by 
doing all of the following:
 Adding the appropriate integration string to the 1001.pbx (and/or 
2001.pbx) file.
Depending on the number of digits in the ID, you use ttt or tttt in your 
integration string.
To capture the inband signalling information you need for the integra-
tion string, you need to use one of the following:
-  A digit grabber/line monitor
- A dummy integration string
Then you edit the trace.out file to see the actual characters sent.
 Creating mailboxes that match the IDs.
The Extension field of each mailbox must direct the call to the appropri-
ate company greeting.
To create the appropriate integration string using a digit grabber:
1. Place a trunk call into Amanda over a CO line (for example CO line 
701).
2. Write down the exact character string sent (as reported by the digit grab-
ber).
For example, it might be #01##701#.

3. Run the Setup utility as explained in “Running Setup” on page 49.
4. From the Configuration Utility menu, press 3 to select Telephone Sys-
tem Integration Patterns.
The Telephone Switch Type screen appears.
5. From the Telephone Switch Type screen, select the name of your .PBX 
file then press Enter.
The Integration Patterns screen appears. Its first line tells the name and 
code (1001 or 2001) for your switching system (if they appear in the 
.PBX file).

OTE:To move from the timeout field to the integration pat-
terns and vice versa, press Page Up or Page Down.
6. Press Down Arrow until the next  line is selected.
7. Type #01##ttt#.
The ttt represents the actual CO line ID number, in this example, 701.
8. Press Down Arrow again.
The description should read “:Direct call from CO trunk.”
9. Press F10 to save, then Esc to return to the C:\Amanda prompt.
10. Next you must create a mailbox with the same ID number. See “To pro-
gram Amanda:” on page 160.
