1.4 SYSTEM OVERVIEW
The TransCell 1900TM System provides an economical means for building out both
coverage and capacity for TIA/EIA-136 TDMA wireless communications. The TransCell
1900TM System uses distributed RF elements to receive and transmit TDMA-based signals
at remote sites, and microwave data links for two-way transport. These signals between
the remote sites and the Base Transceiver Station (BTS) interface at the designated hub
site.
The system software oversees all elements of the TransCell 1900TM System and provides
operational data to a Network Operations Center (NOC). The software also provides the
means to remotely set all system operational parameters and to locally install software
upgrades. All user communications are conducted through an Ethernet® TCP/IP ASCII
interface.
1.4.1 System Configuration
A typical TransCell 1900TM System configuration is shown in Figure 1-1. The basic system
configuration is a Hub/Remote Pair (HRP). Each HRP consists of a Hub Subsystem (either
a Master or Slave) and a Remote Subsystem connected with a microwave data link. Each
Hub Subsystem (Hub 1 through Hub n) is directly connected to a BTS.
Monitoring and control access to the TransCell 1900TM System is provided both locally and
remotely. Local access for monitoring and control of each HRP is provided at both the Hub
and the Remote subsystems in the form of an Ethernet port. Any computer meeting the
minimum configuration requirements (see paragraph 1.4.5.1) with the HRP User Interface
(HUI) software installed and the appropriate list of Internet Protocol (IP) addresses can be
connected for password-controlled access.
At the NOC, the System Element Manager (SEM) software, installed on an appropriately
configured computer, continuously captures alarm data from the Wide Area Network

1.4.5.2 Network Interface
Figure 1-14 shows how the System Element Manager (SEM) and HRP User Interface (HUI)
communicate over the customer’s network with a Hub. The Hubs are connected to a customer provided
DSU/CSU via a V.35 serial connection. The DSU/CSU communicates over a DS0 slot in a T1 line to
another DSU/CSU at the customer’s switch. The DSU/CSU at the Switch is connected to a router over
another V.35 serial connection. A TCP/IP connection is established between the Transcept V.35 Master
SPM in the HRP and the Customer’s router at the Switch. Once this link has been established, the SEM
can connect to the Hub to monitor its health. Likewise a HUI located on the customer’s network can
connect to the HRP to view or change system settings. The Router must be programmed to pass traffic
for the IPs out of its V.35 serial port that is connected to the DSU/CSU.

The SEM software application can be configured to automatically connect to all HubRemote Pairs (HRPs) in the network for monitoring of alarm data. The SEM workstation
communicates with each HRP by connecting to an Ethernet network via a network
interface card.
The SEM Combined Alarm Port can be used to transmit alarms collected at the SEM to the
OSS at the Network Operations Center (NOC). See the Installation and User Manual for
SEM and HUI Subsystems, Transcept Document Number 1000483 for more detail.
1.4.5.4 HRP User Interface (HUI)
The HUI software provides access to the CLI on a HRP. The HUI software operates on the
users PC and communicates with the HRP over an Ethernet connection. A computer with
HUI software installed functions as a monitoring and control point for the TransCell
1900TM System. Remotely located computers may also use this interface to communicate
with the HRPs. See the Installation and User Manual for SEM and HUI Subsystems,
Transcept Document number 1000483 for more detail.

1.4.5.5 HRP Command Language
Command language in the form of ASCII text strings is used to send commands to and
receive messages from the HRP. For example, a command to set the forward attenuation of
Remote RTM carrier number 1 to 4 would be written in HRP Command Language as:
$ SET RTM FWATTEN 1 4
For a complete list of commands see the Installation and User Manual for SEM and HUI
Subsystems, Transcept Document number 1000483.
1.5 SEM STARTUP
1.5.1 User Access
The TransCell 1900TM System provides an operator log-in and log-out capability through
the HRP User Interface software. To log-in, the operator must enter a password, which
defines the authorized user privilege level: The User level typically allows only viewing of
operational parameters and status, while the Super-User level allows changing of
operational parameters. A valid password is comprised of up to eight alphanumeric
characters (no special characters). The HUI validates the password and allows the operator
to gain access to the menus to perform required functions.
The Super-User has the privileges necessary to monitor, control, and modify the system
parameters. See the Installation and User Manual for SEM and HUI Subsystems,
Transcept Document number 1000483 for more detail.
1.5.2 SEM and HUI Workstation Initialization
When power is applied to the SEM workstation, it executes its power-up diagnostics, and
then it starts all the necessary processes, initializes all communication interfaces, and
waits for input from the operator. The HUI requires the user to start the process. Once
started the HUI will start the necessary processes, initializes all communication interfaces,
and wait for input from the operator. See the Installation and User Manual for SEM and
HUI Subsystems, Transcept Document number 1000483 for more detail.
1.5.3 SEM Workstation Shutdown
Normally the SEM operates 24 hours a day, seven days a week. A system shutdown is only
necessary when a SEM workstation is to be replaced or new software is to be downloaded. A
shutdown of the system closes all logging functions, terminates communications links, and
closes all the SEM processes. Refer to Section 4 for a more detailed description.
1.5.4 HUI Workstation Shutdown
To shut down a HUI workstation, the user logs out and then exits from the HUI software in
a manner similar to most other Windows NT based programs, and powers down the
computer. See the Installation and User Manual for SEM and HUI Subsystems, Transcept
Document number 1000483 for more detail.
