1. Introduction
The UM-SNB offers four different interfaces (E1,T1, Serial and Ethernet) connecting customers to high-speed TDM services.
This series have 12 models as following:-
E1 interface model (UM-SNB/E1 , UM-SNB/E1/4w):
It offers two different ways to connect customers a high-speed TDM services with two G.703 E1 interfaces (Balanced 120Ω
RJ45 jack and Unbalanced 75Ω dual BNCs). The G.703 interface will carry from 64kbps to 2.048Mbps.
Serial interface model (UM-SNB/35 , UM-SNB/35/4w):
It offers the customers premise a high-speed TDM service with a DB25 interface. The industry standard DB25 interface can be
configured as a V.35/RS530 or V.36/X.21 connection. The DB25 interface can transfers data up to 5.696Mbps (for 2-wire
model) or up to 11.392Mbps (for 4-wire model).
Ethernet interface model (UM-SNB/L , UM-SNB/L/4w):
It offers the customers premise a high-speed TDM services with a LAN interface. The industry standard LAN interface can
detect a 10M or 100M connection automatically.
(2 in 1)Multi-interface model (E1+T1) (UM-SNB/703 , UM-SNB/703/4w):
It offers two different ways to connect customers a high-speed TDM services with G.703 E1 interface (balanced 120Ω RJ45
jack and unbalanced 75Ω dual BNCs) and T1 interface(balanced 100Ω RJ45 jack). The G.703 interface will carry from 64kbps
to 2.048Mbps for E1 and 64kbps to 1.544Mbps for T1
(3 in 1)Multi-interface model (E1+Serial+Ethernet) (UM-SNB/3in1 , UM-SNB/3in1/4w):
It offers three types of interface: E1 interface (balanced 120Ω RJ45 jack and unbalanced 75Ω dual BNCs), Serial interface
(DB25 female connector) and Ethernet interface (RJ-45 connector).You can select one of the following: (a) E1 interface only
(b)Serial interface only (c) Ethernet interface only (d) E1 and Serial interface (e)E1 and Ethernet interface.
(4 in 1)Multi-interface model (E1+T1+Serial+Ethernet) (UM-SNB/4in1 , UM-SNB/4in1/4w):
It offers three types of interface: E1 interface (balanced 120Ω RJ45 jack and unbalanced 75Ω dual BNCs), T1 interface
(balanced 120Ω RJ45 jack),Serial interface (DB25 female connector) and Ethernet interface (RJ-45 connector).You can select
one of the following: (a) E1 interface only (b) T1 interface only (c)Serial interface only (d) Ethernet interface only (e) E1 and
Serial interface (f)E1 and Ethernet interface (g) T1 and Serial interface (h)T1 and Ethernet interface.
They can be configured and managed via EOC, or menu-driven VT100 compatible Asynchronous Terminal Interface, either
locally or remotely.
The UM-SNB NTU is equipped with an auto rate capability that identifies the maximum line rate supported by the copper loop.
This powerful automatic configuration capability makes installation and service provisioning simple and painless. Further
