C ONFIGURING R ESOURCES AND L INES
Resources
R EGION
For NET3 and NET5 switchtypes. When configuring switches, first identify the region of operation,
and then the country.
C OUNTRY
For the NET3 and NET5 switchtypes. The country in which the system is operating.
G ENERIC N UMBER
For PRI_4ESS primary rate switch type only. The software load (generic # ) the switch is running.
S YNCHRONIZATION T YPE
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 E NCODING M ETHOD
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)
R ESOURCE B ACKGROUND I NFORMATION
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
