		T1, E1, DS-1, DSX, DS3, T3, E3, OC3
100BaseT to DS3 / E3 Converter			A high speed Ethernet access unit. Transport 100BaseT full duplex Ethernet using a DS3 or E3 WAN connection. Inexpensive way to transport Ethernet via the public high speed network. Supports VLAN transparency, MPLS, ISL, and alarming.
100BaseT to 4X E1 Inverse Multiplexer			Inverse E1 multiplexer for Ethernet transport. Transport 100BaseT full duplex Ethernet using up to four E1 lines. Inexpensive way to transport Ethernet by inverse multiplexing multiple E1 lines. Supports VLAN transparency, MPLS, ISL, and alarming.
E-1 Extender			A genuine E1 repeater / extender. No setup, no software; just extends the E1 demarc with reliability and low cost. For T1, see the T-Extender below.
T-1 Extender			A genuine T1 repeater. No setup, no software; just extends the T1 demarc with reliability at low cost.
DCB-AM-3440 Access DCS Mux			Access Multiplexer, equivalent to multiple T1/E1 channel banks rolled into a single chassis. Supports 4 or more T1/E1 interfaces. Supports ATM/Frame Relay. Has 12 DTE slots for FXS, FXO, E&M, serial DTE interfaces, IDSL, HDSL. SNMP GUI, telnet or serial configuration, and cross connect at the DS0 level.
Loop V-4100 Multiservice Access Platform			Used with STM-1 and DS-3 networks, ring or linear, the Loop-V 4100 provides full STM-1 access, OC-3 access, and OC-3 Add-drop. The Loop-V 4100 has full DS0 cross-connect built inside. OC-3, STM-1, DS-3, and sub-rate interfaces make this a full-featured access device that can handle 63 E1 or 84 T1 interfaces.
Loop 4200 IAD & DACS			NEBS Certified Integrated Access Device Multiplexer, DACS, and E1/T1 converter. Has 9 or 28 slot main unit for T1, E1, DS-1, OC-3, V.35, EIA530, RS232, FXS, FXO, Ethernet, ATM, Frame Relay,DSX, or OCUDP/DS-0 interface cards. SNMP, AC or redundant DC power supplies. This is often used as a T1 channel bank replacement.
Loop 4300 Mini-DACS			A genuine "mini" DACS and E1/T1 converter, 2 to 4 T1(E1) interfaces, any port/time-slot to any port/time-slot mapping.
Loop-AM 3400 T1/E1 Quad Mux			Full-featured Quad T1/E1 Mux and DACs with up to 4 T1/E1 WAN or ATM ports, 12 DTE slots that accept cards having 6&10 channel U, 12 channel E&M, 12 channel FXS or FXO, Dual-slot DTE, 6 channel V.35, 5 channel RS-232 (& subrate), MDSL, with SNMP GUI, etc.
Loop-T2500 Fractional T-1 Speed DSU/CSU			Basic to full-featured T1 DSUs with 1 port, 64 or 56XN
FT Fractional T-1 Speed DSU/CSU			Basic to full-featured T1 DSUs with 2 to 4 ports, SNMP, Drop & Insert, 64 or 56XN
T-Monitor T-1 Tap			The T-1 Monitor and tapping device is an electrically active T-1 tap used for lawful intercept, performance monitoring, signal monitoring, and small scale T-1 CALEA installations. While it has active electrical interfaces, it is totally passive to the T-1 data signals. There is no insertion loss with this tap.
T1-TAP Box			The T-1 Tapping Bridge Box provides an impedance corrected T-1 tapping bridge. Works well for some performance monitoring, signal monitoring, and small scale T-1 CALEA installations. Since it is a totallly passive bridge circuit, this inexpensive bridge inserts some loss on the tapped T1, and a lower signal level on the monitor line.
TM-24 Channel Bank			T1 Channel bank and access multiplexer.

		T1 Extenders
T-1 Extender via wire			A genuine T1 repeater. No setup, no software; just extends the T1 demarc up to 5,000 ft (or more with intermediate units) with reliability at low cost.
O-9310 T-1 Via Fiber			The O-9310 extends up to four T1 lines over a single pair of fiber for only $939. The economical solution when there is fiber available.
O-9300 T-1 Via Fiber			The O-9300 extends up to sixteen T1 lines over a single pair of fiber. This solution provides an optional protection pair and a wide varity of interfaces in addition to traditional T-1 DSX-1.
IP-6700 T-1 Via Ethernet			The IP-6700 transports up to 4 T-1 signals with timing plus Ethernet traffic over the IP network.
H-3300 T-1 via wire up to 8 miles!			The H-3300 extends a T-1 over standard T-1 cable up to 8 miles.
