repairs or replacement of components and charge its then
current price, which buyer agrees to pay.
Spectracom shall not have any warranty obligations if the
procedure for warranty claims is not followed. Users must
notify Spectracom of the claim with full information as to the
claimed defect. Spectracom products shall not be returned
unless a return authorization number is issued by Spectracom.
Spectracom products must be returned with the description of
the claimed defect and identification of the individual to be
contacted if additional information is needed. Spectracom
products must be returned properly packed with transportation
charges prepaid.
Shipping expense: Expenses incurred for shipping
Spectracom products to and from Spectracom (including
international customs fees) shall be paid for by the customer,
with the following exception. For customers located within the
United States, any product repaired by Spectracom under a
“warranty repair” will be shipped back to the customer at
Spectracom’s expense unless special/faster delivery is
requested by customer.
Spectracom highly recommends that prior to returning
equipment for service work, our technical support department
be contacted to provide trouble shooting assistance while the
equipment is still installed. If equipment is returned without first
contacting the support department and “no problems are
found” during the repair work, an evaluation fee may be
charged.
EXCEPT FOR THE LIMITED WARRANTY STATED ABOVE,
SPECTRACOM DISCLAIMS ALL WARRANTIES OF ANY
KIND WITH REGARD TO SPECTRACOM PRODUCTS OR

including but not limited to any interruption of service, excess
charges resulting from malfunctions of hardware or software,
loss of business or anticipatory profits resulting from the use or
operation of the Spectracom product or software, whatsoever
or howsoever caused. In no event shall Spectracom be liable
for any direct, indirect, special or consequential damages
whether the claims are grounded in contract, tort (including
negligence), or strict liability.

Introdu tion
This document is the User’s Manual for the EPSILON Switch and Amplifier System E17 and the
EPSILON Switch and Amplifier System E36. (Unless otherwise indicated, details contained
herein apply to both models.)
The SAS-E achieves redundant Time & Frequency source monitoring with intelligent and
automatic switching. It amplifies signals from the selected source and offers a large quantity of
output channels. The SAS-E receives, and monitors continuously, signals from 1 or 2 external
clocks:
•Frequency sine wave signal (from 1 MHz up to 16 MHz)
•1 pulse per second time synchronization (TTL/50Ω)
•Time Of Day message (RS232C serial line)
•External signals
•External clock status (relay contact)
Monitoring results (lost signal and minimal period detection) are reported to the user through
dedicated LEDs and through an Ethernet port. When 2 external clocks are connected, the
SAS-E offers a powerful redundant function by selecting, automatically, the better source. This
automatic selection may be by-passed by the user to allow maintenance or for single clock
operation.
In all cases, the distributed signals — Frequency, 1 Pulse Per Second (PPS), Time of Day
(ToD) — are issued from the same source clock. In automatic mode, when the current selected
source is detected faulty, the SAS-E switches all the distributed signals to the other source. An
Ethernet port allows managing and controlling the SAS-E through embedded SNMP protocol
and/or web server.
The SAS-E is available in two heights to adapt the output capacity to the user’s requirements:
SAS17E — 1u High Version:
8 x frequency outputs, 8 x 1PPS outputs, 2 x ToD outputs, 2 x external signals.
SAS36E — 2u High Version:
16 x frequency outputs, 16 x 1PPS outputs, 2 x ToD outputs, 2 x external signals.
