Introduction to the System 930
The System 930 is a central office T1/E1 telephony simulator. The system provides two
digital interfaces and up to 32 analog ports. The E1 version can be licensed for Euro ISDN
network side, Euro ISDN user side, and QSIG both sides. C S version is not available.
T1 version is available as a separate product. Each interface is configured independent of
the other, permitting both to be identical or different. Splitting interfaces between network
side and user side allows calls to be sent from one interface to the other. Use the reversing
data cable provided with the system to connect interface 1 to interface 2. The functionality
of the system can be explored using features such as the call generator and data analyzer.
The RJ48 pins are wired for connection as the network side. Bantum jacks are also pro-
vided, wired in parallel with the RJ48 pins.
Communication to user screens is by RS-232: 9600 BPS, 8-N-1, XON/XOFF. VT-100 termi-
nal emulation is used for display and keyboard operation. Configuration and status screens
are selected from the main menu. Online help is available from all screens by pressing
<F1>. Screens are quickly configured in real time and shown in real time. Once a screen
has been selected, pressing <ESC> <F4> or <ESC> <F3> skips to the next or previous
screen without going to the main menu.
The factory default condition can be set by typing F CTORY then <ENTER> from this help
screen. Note that all saved system configuration profiles will be destroyed and restored to
their factory default condition.

Abbreviations and Terminology
CD: utomatic Call Distribution. Routes incoming calls to analog ports as required. The system provides
32 CD groups, one for each analog port.
Bearer Channel: Contains digital information for delivery to the end user.
Bonding: Pre-ISDN feature that combines multiple calls to increase data transfer rate. Receiver must
adjust for multipath delays. lso see multirate.
C S: Channel ssociated Signaling. See E1 C S.
CPE: Customer Premise Equipment. Equipment connected to network.
Call by call: Calls are routed by their called number, not the channel they come in on.
DCN: Digital Channel Number.
DNIS: Dialed Number Inbound Service. Inbound calls are routed according to the called number.
DTMF: Dual Tone Multiple Frequency. Tones used for dialing numbers. lso known as touch tones.
Data Channel: Contains signaling information.
E1: Trunk operating at 2.048 MBPS. E1 contains 30 bearer channels, one data channel, and one framing
channel.
E1 C S: E1 Channel ssociated Signaling. The data channel contains a set of signaling bits associated
with specific bearer channels. DNIS is accomplishing using in-band MF (multi frequency) tones. E1 C S
is not supported by this system.
E1 ISDN: E1 Integrated Services Digital Network. The data channel contains ISDN signaling.
Euro ISDN: European ISDN defined by European Telecommunications Standards Institute (ETSI). lso
known as NET5.2 and V5.2. Besides allowing 30 bearer channels, there are some subtle differences
between Euro ISDN and its North merican counterpart. Euro ISDN does not require the user to send a
channel ID information element, giving network side full control of channel selection and eliminating glare.
Channels are always enabled. Overlap dialing is allowed in the user to network direction, eliminating
outbound number configuration on the user side. Provides a sending complete information element that
indicates the called number is complete or there is no called number. Does not allow NF S (non-facility
associated signaling) and hence eliminates the need for backup D-channel signaling. Euro ISDN sends
calling name using the Display IE whereas North merican NI-2 did not support calling name and NI-3
uses the Facility IE.
En-bloc: The called number is sent all at once as opposed to overlap dialing which sends the digits one
at a time. Dial tone is supplied locally.
Glare: User and network sides simultaneously seize the same channel, creating a conflict.
Layer 2: Provides error-free communication between the network and user. lso known as the data link
layer. Layer 2 down indicates that communication has not be established.
Multirate: ISDN feature that uses multiple channels during a single call to increase data transfer rate. This
system supports multirate calls through the redirect facility. lso see bonding.
NF S: Non-facility associated signaling. ISDN feature that allows one D-channel to provide signaling for
multiple DS1s.

The System 930 Help Menu
Abbreviations and Terminology (continued)
Overlap: The called number is sent one digit at a time as opposed to en-bloc dialing which sends the
digits all at once. Dial tone is supplied by the near end.
PRI: Primary Rate Interface. ISDN over T1 or E1.
Pulse Dialing: Dialing accomplished by breaking of DC current, or the analog or digital equivalent. Pulse
dialing is not supported by this system.
QSIG: Switch emulation for linking PBXs on a private network. Similar to Euro ISDN.
Remote larm: larm bit sent by E1 carrier to indicate loss of frame synchronization.
RBS: Robbed Bit Signaling. See T1 RBS.
Switch Hook Flash: method for holding and transferring calls from one analog port to another. ctivated
by depressing the receiver hook for one second. This product supports this feature.
T1: Trunk operating at 1.544 MBPS. Contains 24 channels.
T1 ISDN: T1 Integrated Services Digital Network. T1 trunk containing 23 bearer channels and one ISDN
signaling channel.
T1 RBS: T1 Robbed Bit Signaling. T1 trunk containing 24 bearer channels and no data channels. Signaling
is accomplished by stealing one bit from each bearer channel.
Unframed Ones: E1 carrier containing all ones, including the framing channel.
Standards
The signaling standards used by this system are: Layer-1: ITU-T G.703, G.704, G.706. Euro ISDN (Net5):
ETS 300 102-1, ETS 300 102-2, ETS 300 104, ETS 300 125, and ETS 300 172. QSIG: ETS 300 001,
ETS 300 170, ETS 300 172, and ETS 300 239.
VT-100 Display Standards: The VT-100 display codes used by this system are ^[[2J for clear screen,
^[[0m for normal video, ^[[7m for reverse video, and ^[[row;columnf for row and column screen
position. ^[ represents SCII ESC.
VT-100 Keyboard Standards: The VT-100 keyboard codes used by this system are ^[OP for F1,
^[OQ for F2, ^[OR for F3, ^[OS for F4, ^[[ for up, ^[[B for down, ^[[C for right, and ^[[D
for left. ^[ represents SCII ESC.
Calling Name
There are two methods for sending calling name: Display IE (information element) and Facility IE.
In North merica, Display IE is sent in codeset 6 (network specific) because it is a proprietary method.
This works for names originating from the network or user side. In Europe, ETSI recommends sending
Display IE in codeset 0 (normal). The Display IE is sent from the network to user side only. In either case,
calling name is sent in setup messages. Coding of the display IE is very simple. Here is an example:
Coding of Display IE for Calling Name  BC:
0x28 Display IE
0x03 IE Length
0x41 Display Information:
0x42 Display Information: B
0x43 Display Information: C
Use of the Facility IE follows the Telcordia GR-1367-CORE recommendation. This service is part of the
1996 NI-3 feature offering and is available on National and 5ESS Custom PRIs. Calling Name consists of
three separate features: Calling Name Delivery, Privacy of Calling Name, and Electronic Directory Service.

System 930 E1 Version Reference Document Issue 7, March 2001
Gordon Kapes, Inc. Page 9
The System 930 Help Menu
Calling Name (continued)
Calling Name Delivery provides name information to a subscribed terminating CPE. Name characters are
obtained from a name database based on the calling party number. Privacy of Calling Name allows an
originating CPE to signal on a per-call basis whether the calling name should be displayed. Electronic
Directory Service allows an originating CPE to send original calling name to intrabusiness group calls.
The System 930 supports the first of these features: Calling Name Delivery. This feature is implemented
using the ROSE (Remote Operation Service Element) invoke service component of the facility IE.
Calling Name Delivery is a two-step process. The first step depends on whether the calling number is
available and whether the privacy indicator is turned on or off. If the calling number is missing or the
privacy indicator is turned on, a facility IE is sent in the setup message indicating that the name is not
available or is private. If the calling number is present and the privacy indicator is turned off, a facility
IE is sent in the setup message indicating information following. This gives the central office time to look
up the calling name. The central office then sends a facility message containing the facility IE with the
calling name.
Coding of the facility IE is very complex. It uses SN.1 ( bstract Syntax Notation One), which is a database
language defined in ITU-T X.209. Here are four examples:
