Introduction
To route traffic from one device to another device in the NMS, you must define DS0 maps (also called an
internal connection or cross-connection). An internal cross-connection carries traffic between the two external
devices via a card in the system. The external devices can be (but are not limited to) a T1/E1 NTU, a
G.SHDSL customer premise equipment (CPE) modem, or another blade in the same cPCI chassis in which
the card(s) in the NMS is installed.
External devices can connect to a device in the NMS via a T1/E1 WAN port, a DSL port, an STM-1 trunk, or
an H.110 port. (A device will connect to an H.110 port via the card’s interface to the H.110 bus in the cPCI
chassis midplane). Each DS0 mapping defines a one-to-one connection between a selected number of timeslots
on one port and a corresponding number of timeslots on a different port.

Map Types in the FS6300
There are three types of maps in the FS6300 NMS.
•
Same-Card Maps:
A map created between any two TDM ports (T1E1, GSHDSL, iDSL) on the same card.
•
Inter-Card Maps:
A pair of maps created between two TDM ports on two different cards, in the same 2U
or 4U chassis unit, or on two different cards in the same segment of a 6U chassis unit.
Inter-card maps use the H.110 back plane ports and time slots.
H.110 Tx Port number and Time slots used by one map are used as Rx Port Number and Time slots by the
second map. Similarly, the Rx Port and Time slots used in one map are used for Tx on the second map.
To create inter-card maps, FS6300 auto-allocates H.110 time slots from the chassis back plane.
•
End-to-End Maps:
A map between ports of any two cards placed in different ForeFront chassis/chassis seg-
ments.

By default, the
Network Maps > FS6300 Geographical Areas
view displays maps between areas and devicesin
the NMS. Right-click on a link to view link details and properties such as alarm severity level, connection type,
source and destination information, and time slots.
