2.2 GENERAL PRODUCT DESCRIPTION
The

Model 2720/I is a single port T1/FT1 CSU/DSU
with Ethernet Bridging that provides high-speed LAN-to-WAN connec-
tivity. Plugging directly into the 10Base-T port of a hub or LAN switch,
the NetLink-T1™ provides T1 or FT1 access at connection data rates
of 1.544 Mbps, nx64, and nx56 (n=1 to 24 channels). The Netlink-
T1™ is an excellent choice for internet access as well as LAN-to-LAN
services.
The Netlink-T1™ provides digital access to a local WAN service
provider or directly between two facilities over a dedicated 4-Wire cir-
cuit. WAN bandwidth, framing and coding options are programmed via
externally accessible DIP switches or via a VT-100 type terminal using
the rear-mounted EIA-232 Control Port. Netlink-T1™ supports D4/ESF
framing options and AMI/B8ZS/B7ZS line coding. Netlink-T1™ also
supports a full range of system and diagnostic features that make sys-
tem setup easy. The Ethernet Bridge in this unit requires no configura-
tion at all.
The NetLink-T1™ provides T1 terminations over a modular RJ-48C
jack and comply with jitter tolerance capabilities as specified in ANSI
T1.403 and AT&T TR62411. External power options include 120VAC
and universal interface 100-240VAC. 48VDC and rack card versions
are also available.
