Help-Desk Management

Edit / [top]

Most Help-Desk Management systems are similar to Trouble-Ticketing systems, except that they add a variety of customer tracking features. Minimally, this include an address-book which logs detailed customer relationship info, so that support staff can understand how past relationships with the customer went, can recognize high-priority/important customers quickly, and understand customer quirks for special treatment (i.e. to easily "know the customer"). Call tracking systems usually include search capabilities for locating related calls or trouble tickets, and/or referencing FAQ's based on the problem description (aka a "Knowledge Base"). These systems might also provide call tracking (time spent on the phone), time-tracking (hours spent solving the problem), and may include mechanisms to automatically bill the client for hours worked. Premium systems add some workflow and escalation capabilities, so that unresolved tickets can follow either the normal workflow procedure, or be escalated to higher levels for team-lead/management/special attention & resolution.

HSCSD

Edit / [top]

High Speed Circuit Switched Data (HSCSD) is an enhancement of data services ("Circuit Switched Data - CSD) over all GSM (2G) networks. It allows you to access nonvoice services at 3 or more times the rate normally associated with 2G, which means subscribers are able to send and receive data from their portable computers at a speed of up to 43.2 kbps on fully deployed networks.

The HSCSD solution enables higher rates by using multiple channels, allowing subscribers to enjoy faster rates for their Internet, e-mail, calendar and file transfer services.
