DS3 Equivalent to 28 T1 Lines
DS3 service at a signaling rate of 44.736 Mbps is the equivalent
of 28 T1 lines at their signaling rate of 1.544 Mbps. Because
of the strict synchronization of TDM services, 28 T1 lines may
be multiplexed into a single DS3 service.
When to Use Pseudowires
A pseudowire is a virtual "circuit" that emulates a
traditional digital telecom service but on a packet switched network.
MPLS networks are especially suitable for pseudowires. By using
a pseudowire circuit, you can get the point to point connectivity
you desire without having to re-engineer your facilities to accommodate
a different protocol network.
DS3 for Call Center Telephony
DS3 voice service can support up to 672 simultaneous telephone
conversations without blocking. If your call center or large corporate
PBX system requires this number of outside lines, DS3 is likely
far more cost effective than ordering the equivalent 28 T1 lines.
How DS3 Relates to OC3
DS3 is a digital signal level originally developed to support
the copper based T-Carrier digital telephone trunking system.
DS3 offers about 45 Mbps of bandwidth . OC3 is a SONET optical
carrier standard running at about 155 Mbps. An OC3 link can transport
up to 3 separate DS3 services.
Difference Between DSL and
DSL means Digital Subscriber Line and is a shared bandwidth service
offered on a "best effort" basis by telephone companies.
DS3 is a professional telecom service with a fixed bandwidth of
45 Mbps both upload and download. DS3 is usually sold with on
a contract with a service level agreement.
