Overview
GL's Octal & Quad T1 E1 boards are high density and provide Four (4) or Eight (8) RJ-48 T1 E1 ports and multiples thereof. For example,
configurations of 8, 12, 16, 64 T1 E1s in a single rack are possible.

Main Features
- T1 or E1 interfacing – Software Selectable
- PCI Express x1 Lane/Board
- TDM, ISDN, SS7 – High Density Voice
- VoIP, Frame Relay, Multilink Frame Relay, PPP and Multilink PPP, HDLC
- Most all “basic applications” and “special applications” are available for Quad and Octal T1 E1 cards
- Call Recording, Generation, and Monitoring for hundreds to thousands of calls in one platform
- Windows and Linux Drivers for Open Source Applications
- Media (VoIP) Gateway, IP PBX, and IVR Applications i.e. Asterisk (TM)
- Router with Multi T1 E1 WAN Interfaces i.e. MLPPP (Multi Link PPP)
- Supports “Cross-Port Through” and “Cross-Port Transmit” Modes – these configurations make cabling with Drop/Insert and Fail-Safe Inline
Monitoring very easy
- High Density and High Speed – The boards (with Direct Memory Access) are significantly faster and significantly more efficient
- Octal boards are compatible with dual, quad, and higher core motherboards and software that simulate dual and quad cores (hyper-threading)
- Support for all existing T1 E1 applications including comprehensive Voice, Data, Protocol, Analog, Digital Analysis / Emulation, and Echo and Voice Quality testing
The cards are available with user-friendly GUI for Windows® XP and Windows® 7 operating systems with support for almost all existing T1 E1 Analyzer
applications including Comprehensive Analysis / Emulation of Voice, Data, Protocol, Digital, and Echo Testing.
GL's offers other popular forms of T1 E1 analysis hardware such as Portable USB T1 E1 Analyzer with dual T1 E1 ports & smallest
form factor, tProbe™ T1 E1 Analyzer Unit - an enhanced version of USB based T1 E1 VF & Serial Data analyzer with
expansion capabilities, Universal T1 E1 Analyzer Boards - a dual port PCI based T1 E1 analyzer offering higher speed factor and
smaller dimensions. Please call us for more information on these.
Comparison and advantages of the new Quad and Octal Cards over Dual T1 E1 Universal Cards are given in the following table.

Accompanying Basic Software / Features
GL’s Octal/Quad T1 E1 Analyzer comes with “basic applications” for basic testing needs and “special applications” that extend the capability far beyond the
most expensive T1 E1 Data testers. For example, capturing and transmitting an entire raw T1 E1 signal simultaneously on two full duplex ports, or performing
ISDN emulation, or SS7 analysis, or analyzing echo and voice quality on voiceband channels, to name a few. A list of all the basic applications and other
optional applications (requiring additional licenses) are listed here -

Loopbacks
Cross-port Through Loopback
This mode is similar to the standard Outward Loopback except that the signal received on Card 1 (Port 1) is transmitted out onto Card 2 (Port 2). Likewise the
signal received on Card 2 (Port 2) is transmitted out onto Card 1 (Port 1). This feature allows monitoring T1/E1 lines in-line while still being protected from loss of
power to the board. This mode is implemented entirely thru relays and eliminates complex cabling.
Cross-port Transmit Mode Loopback
In this Mode, the data that would normally be transmitted on Card 1 (Port 1) is diverted and transmitted on Card 2 (Port 2) and the data that would normally
be transmitted on Card 2 (Port 2) is diverted and transmitted on Card 1 (Port 1). The receive paths are completely unaffected. This mode is particularly useful for
Drop and Insert and Error Injection applications in which the board analyzes and may insert traffic running between two pieces of T1/E1 equipment. This feature
also eliminates complex cabling.
