Specialized Enhanced Vertical Services: X.25 (X.25 variants) Mediation with IP
The DT-4180 is also a Network Applications Computer. It applies customer specific protocol
operations (protocol translation and termination) of network connections that require such a
function in a distributed network.
The resident X.25 mediation application provides a greater degree of mediation by allowing a telnet
client to interface on a per Virtual Circuit (VC) basis to X.25 (x.25 variants) network elements.
The X.25 mediation application supports:
! X.25 pass-through for Virtual Circuit (VC) aggregation
! Individual configuration of each X.25 Virtual Circuit (VC) as a PAD or a PASS-THROUGH interface
! Interfaces for the MacStar Operations Support System (OSS)
! Record Boundary Preservation (RBP) protocol
! Switched Virtual Circuit (SVC) hunt groups across X.25 lines, allowing fault tolerant X.25 links
to be established.
Time Slot Router (TSR) as a Channel Bank Replacement
With the TSR interface, T1, E1, or J1 Time Division Multiplexed (TDM) formats are supported. Each
time slot may be uniquely routed on the IP WAN while individual CODECs may be installed for load
optimization.
As a Channel Bank replacement, the DT-4180 can help reduce maintenance costs, power needs and
free up valuable equipment floor and rack space.
