Important Safety Instructions
Safety Information:
Installer and User WARNING
The device is to be installed and operated at a “fixed location”. The term
"fixed location" means that the device is physically secured at one location
and is not able to be easily moved to another location.
It must be located - (for indoor RPs) up on or near the ceiling away from
users or bystanders – (for outdoor RPs) on the roof top site, pole, building, or
traffic light away from users or bystanders. It must be mounted in a manner
to ensure that a minimum separation distance of 20cm is normally
maintained between all users, bystanders and the antenna (including any
radiating structure).
The installer may be required to perform an MPE evaluation and an
Environmental Assessment (EA) of the location at the time of licensing per
CFR 47 Part 1.1307. Fixed mounted antennae that are co-located with other
antennae must satisfy the co-location requirements of Part 1.1307.
Limits:
The limit for general population/uncontrolled environment exposures is 1
mW / cm 2 for the band 1500-100,000 MHz.
MPE evaluation:
The following calculations are provided for the more restrictive limit:
uncontrolled environment/general population.
The calculated minimum safe distance, Radii(cm), is approximately 10 times
lower than the minimum required installation distance of 20 cm per Part 2.1091.

RPC/RP Manual
Therefore, the transmitter model numbers EA7H74B and EA7H75B complies
with the MPE requirements by providing a safe separation distance between the
antenna (including any radiating structure) and any persons.
The calculations were performed using formulas found in OET Bulletin 65
Edition 97-01(1997).

2.1 General Description
The Radio Port Controller (RPC) functions as the controller and power distributor
for the Radio Ports (RPs). It is also the concentrator of the speech paths and the
protocol converter for the PHS protocol and the Q.931 protocol. It has Dual Tone
Multi Frequency (DTMF) senders for dialing to the Local Exchange (LE) through
the Central Office Terminal (COT). In addition, the RPC synchronizes the
associated RPs by extracting the synchronous clock from the E1 line connected to
the COT and distributing it to all of the associated RPs.
RPCs can be co-located with a COT or located remotely and communicate with
the COT using E1 transmission over:
•
•
•
High Density Subscriber Loop (HDSL)
Fiber Optic Transmission (FOT)
Digital microwave radio
Figure 2-1 presents an overview of the RPC and RPs in the WLL system.

2.1.1 Main RPC Features
An RPC consists mainly of four types of function modules:
•
•
•
•
One ECNT (Enhanced Control) module
Up to four E1IF (E1 Interface) modules
Up to eight RPIF (RP Interface) modules
One APL (Application Software Loading) module - Optional
Figure 2-2 displays the four types of the function modules in the RPC.

Figure 2-2: Function Modules inside the RPC
Each RPC can handle traffic loads of up to 120 simultaneous telephone calls.
Four E1 trunks connect to the COT side and support 30 subscriber channels each.
In normal traffic conditions, a single RPC can service approximately 1000
subscribers.
The RPC is monitored and controlled from the network management system
connected to the COT. With this setup the program data, the operation data, and
the system parameters can be changed and the alarm information and traffic data
can be gathered easily.
2.1.2 RPC Module Descriptions
The following sections describe the RPC component modules, including the
physical configuration, Light Emitting Diodes (LEDs), and switch operations.

2.1.2.1 Enhanced Control Module
The ECNT module provides the Operation, Administration and Maintenance
(OA&M) support for the RPC. In addition, it provides the time slot cross connect
switch for communications between the E1IFs and the RPIFs. Figure 2-3
represents the ECNT functions.
Figure 2-3: ECNT Block Diagram
The ECNT module performs the clock synchronization by generating a
synchronized clock from the extracted clock signal from the E1 line on the E1
interface card and delivers it to the RP lines on the RP interface cards.
The RPC uses a control bus via the ADPCM highway on the mother board to
synchronize the system. The Control Bus is an 8-bit mixed bus address with data
and First-in First-out (FIFO) type bus. The main CPU on the ECNT card, the
local CPUs on E1 Interface cards and the RP-interface cards are all connected by
this bus. The main CPU on the ECNT card controls the bus.

2.1.2.2 E1 Interface Module
The RPC connects to the COT through a 2.048 Mbps E1 Interface that carries all
the control and voice channels, that is, PCM encoded voice or voice band data,
between the COT and the RPC. The E1 Interface (E1IF) module communicates
externally with the COT through 1 G.703 E1 interface and uses Q.931 non-facility
associated signaling protocol.
Transmission between the RPC and RP is based on a proprietary, echo-canceled
transmission standard, which is similar to the recognized G.961 ISDN standard.
The E1IF provides the speech coding conversion between A-law PCM from the
COT and Adaptive Differential Pulse Code Modulation (ADPCM), which is ITU-

Rec.726 compliant, from the RP. It supports 32 kbps channel signaling for
encoded voice and voice band data calls.
In addition, the E1IF communicates internally with the Radio Port Interface
(RPIF) module for interfacing RPs through the backplane busses and the switch in
the ECNT module.
The E1IF module is an E1 module (E1M) that provides 4 E1 connections to the
E1 network. The E1 module has the following functions:
•
•
•
•
•
•
Originates/terminates 4 G.703/G.704 2.048 Mbps E1 interface
Provides 75 ohm unbalanced interface
Provides LEDs for module and port status and alarms

Monitors performance of each E1 line
Detects errors and alarms on the E1 lines.

2.1.2.3 Radio Port Interface Module
Each RPC controls and feeds a maximum of 32 RPs. The RPC connects to the
RPs through a 2-wire proprietary interface. Line power feeding from the RPC
provides a power source of 116V DC to the RPs.
The RPC controls the RPs via 8 RPIF modules. Each RPIF module provides an
ISDN Basic Rate interface to 4 RPs. The RP is extended from the RPC to a
maximum distance of 5.0km using a pair of φ0.5 wires and approximately 3.5 km
using a pair of φ0.4 wires.
The Radio Port Interface (RPIF) module communicates externally with four RPs
through ISDN Basic Rate Interfaces (BRI). In addition, it communicates

2.1.2.4 Application Software Loading Module
The Application Software Loading (APL) Module facilitates the downloading of
software in the event there is a problem in loading software. It permits the
upgrading of the ECNT module firmware. In addition, any software upgrades can
be downloaded remotely from a PC to an RPC. The APL module is installed only
when the software or firmware needs to be upgraded or downloaded. It is not
intended to remain in the system during the normal operations.

2.1.2.5 ADPCM Highway
The ADPCM (Adaptive Differential Pulse Code Modulation) highway is the
synchronous time multiplex digital voice/data path, and consists of up-stream and
down-stream for Time Switch on the ECNT card. Time Switch and the digital
voice and data paths on the E1IF cards and the RPIF cards are connected by the
ADPCM highway.
There are 8 ADPCM highways in an RPC. Half of them are assigned for E1IF
cards, and the rest are assigned for RPIF cards. The bit rate of an ADPCM
highway is 2048 kbps, and the frame repetition rate is 8 kHz.

8. Connect the coaxial cable with an SMB coaxial cable plug having an
impedance of 75 ohms into the E1IF connectors on the back of the RPC, as
shown in Figure 2-17
9. Connect the cable with a Champ plug to the RPIF connector on the back of
the RPC. Refer to Figure 2-17. Table 2-1 provides the maximum cable
lengths between the RPC and the RP for 2 different wire gauges. Refer to

NOTE: Be sure to use a twisted pair cable or a 2 pair twisted cable. Avoid any 2
pair twisted cable splits before connecting cables.
10. When the RP and E1 cables are connected, attach the cabling to the supports
with tie bands. Refer to Figure 2-18.
NOTE: Tie Bands are to be prepared on-site.

11. Install the modules in the RPC slots according to the labels on the cabinet.
Refer to Figure 2-19 for the slot assignment.
NOTE: The APL module is installed only when the software upgrades are
unsuccessful without it. It is not intended to remain in the system during normal
operations.
