EXTender 6000 Quick Installation Guide 7
Prerequisites for Installation
You must meet the following requirements before installing the EXTender 6000:
Network Requirements
You must install and configure appropriate network terminating devices at both the corporate facility
and the branch office. Both network-terminating devices must be fully functional and both must
support an RS-232, V.35, or RS-530 synchronous, asynchronous or Voice over IP (VOIP) interface.
If you use an asynchronous connection, you must install the appropriate ISDN Terminal Adapters
(TAs), from the list below. The TAs must be operational at both the corporate facility and the Branch
Office. This list is complete as of the release date of this document. Refer to the MCK’s Web site:

EXTender 6000 Quick Installation Guide 8
ISDN Requirements (for asynchronous connections)
Before you install your units, order an ISDN BRI line at both the local site and the remote branch office.
This ISDN line should be capable of the following:
The ability to make two “data” calls, one on each B Channel of the ISDN line.
If long distance, both “data” calls must be set up as “data”.
Note: Confirm this with your long distance provider when you order your ISDN Line. A call is defined
as “voice” or “data” in the setup message.
Information for the System Administrator
When your ISDN BRI line is installed, you receive two Service Profile Identifiers (SPIDs) and two
Directory Numbers (DNs). Provide these numbers to the System Administrator. Record the SPID and DN
information and keep it in a safe place for reference when installing the ISDN TAs. If you do not have the
SPIDs or DNs, you cannot program the ISDN TAs.

* MCK’s IP-based products utilize VOIP technology to deliver remote voice
solutions. The voice quality of these solutions is dependent on variables such as
available bandwidth, network latency and quality of service (QoS) initiatives, all
of which are controlled by the network and internet service providers. Because
these variables are not our control, we cannot guarantee the performance of the
user’s IP-based remote voice solution.
