Pendar Pajouh's 118 system is an integrated set of network equipment, hardware and the operator and management software required for the 118 directory-assistance service. It was designed on the company's many years of experience in the 118 field and is flexible enough to cover requested changes and required reports. Connection to the public switched telephone network (PSTN) is made via analogue lines or an E1 link, based on VoIP technology.

Capabilities

• Connection to the PSTN via analogue lines or an E1 link, based on VoIP
• Support for various Media Gateways such as Planet and Cisco, compatible with the SIP standard and a range of audio codecs
• Support for hardware and software SIP proxies
• Operators can work from home via a LAN Extender
• Automatic logging and recording of events
• Centralised data storage and online operator access to the central database
• Smart search tailored to operator needs
• Scheduled playback of system messages
• Online monitoring of operator responsiveness
• Data entry individually or in batches

Pendar Pajouh's Unified Voice Messaging System (UMS) is a collection of hardware, software and web/Windows services that operate under unified management as an Application Service and a Soft Switch. The system runs the following telecom services concurrently and in an integrated way:

• 190 public-relations line
• Voice mailbox and voice recorder (Voice Mail)
• Debt-notice service
• Istikhara (religious guidance) service
• Speaking clock
• IVR announcement of postal and national ID codes
• Lost-and-found postal system
• Quranic-recitation service
• Religious prayer times
• Contact Center service
• Status-based nodes
• Call-origin-based nodes
• Notification system
• SMS sending
• 1818 service
• NOC

Telecom operators deal with vast volumes of data and information flows that feed their billing processes. These processes are complex and built on composite automation, and given the high data volume, data integrity can be compromised during transfer and processing. Numerous factors — fraud, call-routing errors, rating and charging errors, billing-system errors, interconnect payments and poor system integration — cause revenue loss. Running a Revenue Assurance (RA) process addresses all of these factors and ultimately optimises collected revenue.

Revenue growth

• Fewer un-billed cases
• Better collection order without losing customers
• Stronger pervasive controls to prevent revenue leakage

Lower costs of uncollected receivables

• Reduced bad debt through overall customer review
• Customer fraud management
• Lower credit exposure to delinquent customers

Working capital & interest

• Shorter billing time and less working capital tied up in the billing cycle
• Faster cash collection and fewer days of outstanding receivables
• Rapid dispute resolution
• Better turnover of customer credit balances

Lower operating costs

• Improved cash-cycle processes
• Realignment of risk-management duties

The Hotbilling system is implemented in two stages: a Mediation stage and a Rating & Billing stage.

Overall capabilities

• Full collection of all XDR types from every network element, with automated interfacing
• Centralised rating and tariffing at the billing centre, with high flexibility
• Subscriber bill calculation based on XDRs
• Analytical reporting on subscriber behaviour and network status
• Inter-operator calculations
• Subscriber bill issuance
• Detecting and preventing revenue leakage and fraud
• Optimising the billing process and improving subscriber satisfaction

a) Mediation system

Mediation is responsible for collecting data (XDRs) from the switch infrastructure and passing it to the normalisation stage. It connects to telecom switch infrastructure, and its interface components can accommodate future expansion and various infrastructure vendors. Call data can be collected both online (file transfer over the network) and via CD, with support for low- and high-capacity switches and other network operators.

b) Billing system

A system that intelligently performs all of the telecom company's current manual and automated fixed-line billing operations; supporting Hot Billing, Billing Center and mid-cycle cut-off indicators, with no limit on the number of users, numbers or services. It prevents abuse of international transit and traffic termination, covers inter-operator interconnection, and helps control the telecom company's uncollected revenue.

Pendar Pajouh's control-centre system is a voice-and-web system designed to implement part of the data-centre TMN, comprising two main services.

Voice IVR subscriber-contact service

• 24/7 response every day of the year
• Voice ticket logging with a tracking number announced
• Removing busy tones on control-centre lines
• Announcing specific outage states (e.g. downtime) to subscribers
• Automatic email to the subscriber announcing current status
• Connecting to fault-resolution staff when needed

Web-based office-automation service

• Ticket creation and integration with the IVR to receive new tickets
• Managing ticket status changes
• Various reports, including the SLA report
• Removing bureaucracy and speeding up data-fault resolution

A contact centre based on VoIP technology, supporting 512 concurrent calls.

Capabilities

• Connectivity with various softphones, IP phones and gateways
• Fair call distribution and configurable decision rules for different queues
• Transfer, Hold, DND and similar features
• Outbound calling and an auto-dialler robot (bulk call dispatch with configurable conditions)
• Advanced monitoring and supervision systems
• Voice Mailbox system with unlimited voice boxes
• Text-to-Speech module for English
• Easy design and editing of call trees with question/answer nodes, date- and time-based decisions, and message record/playback
• Various reports and a report builder

The Fixed-Line SMS system (FSMS) provides the infrastructure needed to send and receive SMS on the fixed telephone network, complementing the mobile SMS system.

With this system, messages can be sent and received from a fixed line to another fixed line, to a mobile phone, or to other networks such as email. To use the service, the fixed-line handset must be equipped with SMS send/receive capability so it can connect to the fixed-line SMSC via the PSTN.

Telecom companies strive to maximise efficiency and minimise human error and required staff by centrally and remotely controlling and maintaining their equipment. Given the diversity of telecom switches in Iran and the need for specialist expertise for each type, an efficient system for the comprehensive management of telecom centres is essential. The centralised management systems of major vendors (such as Huawei and Siemens) manage only centres of their own brand, and only through a northbound interface.

Pendar Pajouh, by providing comprehensive management software, has achieved centralised management of all domestic and foreign switches without the need for a northbound interface; a dedicated communication gateway is designed to control and manage each switch, covering every switch active on the country's telephone network. Beyond the switches, environmental parameters, power sources and the cable network are also managed by the system, and an alarm appropriate to the type of fault is reported to the relevant operator. A fault-tracking (ticketing) system, trunk testing and traffic measurement, and various system and office reports are also provided.

System components

• Gateway software running on a computer near the switch
• Central management-and-maintenance software running on a server at the control centre

Central-software modules

• Fault management: viewing and monitoring alarms and events, their history and details, and a visual connectivity graph showing path faults
• Performance management: traffic measurement, path-graph logging and link/trunk reports
• Centre office-information management
• System access-security management
• Fault-tracking module with manual or automatic ticket creation and assignment to the responsible operator

The mechanised personal mailbox system, designed by Pendar Pajouh Electronic Engineering, is intended to honour clients and postal managers and provides full oversight of every stage.

Features

• SMS sending
• Subscriber calls to the IVR numbers
• System calls to the subscriber announcing parcel arrival by phone, email and SMS
• Recording and checking incoming-parcel information and viewing empty box capacity
• Various reports
