CONFIGURING RESOURCES AND LINES

Resources

REGION

For NET3 and NET5 switchtypes. When configuring switches, first identify the region of operation, and then the country.

COUNTRY

For the NET3 and NET5 switchtypes. The country in which the system is operating.

GENERIC NUMBER

For PRI_4ESS primary rate switch type only. The software load (generic #) the switch is running.

SYNCHRONIZATION TYPE

For Primary adapters only. Every framed transmission line requires a clock source from which it must derive the appropriate bit timing and channel timing relative to the start of a frame. For most CPE gear, the clocking is derived from the received signal and the transmission clock is thus a “slave” to the network. However, if the line is to provide its own clocking, it must derive a clock from an internal source rather than a received signal. The line is then a “master” clock source.

PCM ENCODING METHOD

For DM-24 and DM-30 adapters only. Pulse Code Modulation (PCM) is a common method of encoding an analog signal into a digital bit stream. PCM encoding choices are:

•mu-law (the PCM encoding standard used in Japan and North America)

•A-law (the PCM encoding standard used in Europe)

RESOURCE BACKGROUND INFORMATION

The basic rate (BRI) resource directly terminates a standard USOC RJ45 connector. It is supplied with a standard S/T interface. A U interface option is not available for this adapter. The BRI resource supports 1 or 4 connections/ports depending on which option you purchase. It provides support for the following switch types:

•NTT

•5ESS

•DMS100

•NI1

•1TR6

•NET3

•Definity

•Legend

•TS0-13

BASIC RATE NET is a test facility. This should not be configured as a resource type.

The T1-E1-PRI can be used for any T1, E1, or PRI resource, and directly terminates a standard USOC RJ45 connector. It is supplied with a standard S/T interface and supports one port. It also provides support for the following switch types:

•NTT

•4ESS

•5ESS

•Definity

•DMS100, DMS250, DMS500

•SL100

•NET5
