ADC’s ThinMux
™
product family helps carriers build today's access networks that can easily
adapt to meet tomorrow's needs. Only the ThinMux products provide a single platform to
encompass many universal standards (SONET/SDH, DS3, T1/E1). As bandwidth requirements
increase and network technologies change, ThinMux is quickly and easily upgraded by
replacing the multiplexer card within the chassis. Complete flexibility in delivering unique

multiplexer cards that offer wider standards compliance, higher bandwidths and optical network interfaces
• Investment Security: a single chassis, with multichassis compatibility of the multiplexer cards,
ensures that any investment will be protected long into the future
• One Platform Accommodating Worldwide Networks: service type is software selectable with T1/E1
applications multiplexed onto a single platform
• Significant Cost Reduction In Providing T1 or E1 (or mixed) Services: standardization onto a single
platform provides tangible benefits through no incurred costs for additional provisioning, servicing,
inventory, training or obsolescence
• Easy remote management: optional HiView Station Graphical User Interface (GUI) Application
• Flexible remote management: TL-1, VT100 Craft Screens or SNMP with HiView manager application
software
• Multiple management connections: RS232 or 10Base-T Ethernet

ThinMux
Applications
Bundled Bandwidth
Unbundled T1 Usage
The industry leading size and high service density enables ADC’s ThinMux product family to
cost-effectively aggregate low speed T1 or E1 subscriber interfaces onto one high-speed DS3
or STS-1 network interface. The rack space in today’s CLEC/DLEC co-location cages or ILEC
Central Offices is at a premium – minimizing the space requirements while maximizing the
service density significantly lowers service provisioning costs. A fully protected ThinMux
multiplexer platform occupies a single rack unit to provide up to 28 T1 or 21 E1 interfaces.
Integrated forced air cooling enables shelves to be stacked together with no wasted space for
ventilation.
Concentration of many low speed access network interfces into a single higher speed
interface results in a more cost-effective use of capital intensive equipment such as a voice
switch or a SONET ADM Transport Network Element. By utilizing the ThinMux’s flexible
